games/NXDoom: Initial port of Chocolate DOOM to NuttX.

Browse source 
This commit includes a (highly) modified version of Chocolate DOOM which
can run on NuttX. The majority of the modifications were made to pass
the NuttX style check. Some small modifications have been added to
support keyboard input, render graphics to frame buffers and directly
use the POSIX interfaces NuttX supplies, stripping out Windows/Mac stuff
and any references to SDL.

NOTE: Sound is currently not supported in any capacity, nor is the
networking stuff. A lot of Chocolate DOOM code was stripped out since it
was unused. If there is a need/desire to add it back later, the original
Chocolate DOOM source can be used as a reference.

WARNING: The NuttX keyboard codec is incredibly non-standard and so
there are problems translating from X11 keys to NuttX ones to play DOOM.
Right now, the CTRL key for firing doesn't work because the NuttX codec
has no concept of it. The NuttX codec should be modified (and other
input devices supported), but at the time of this port I am not
sufficiently comfortable doing so since I am afraid of breaking other
things in the kernel.

NOTE: This port (and likely the original DOOM) seems to be written with
32-bit computers in mind. As such, most things are given the type of
natural `int`, even when a single byte might do. There are significant
size optimizations that could be made to make this more suited to
embedded devices that NuttX typically runs on.

Thanks for contributing to Chocolate Doom! Whatever your contribution,
whether it's code or just a bug report, it's greatly appreciated.
The project is governed by the
[Contributor Covenant](http://contributor-covenant.org/version/1/4/)
version 1.4. By contributing to the project you agree to abide by its
terms. To report violations, please send an email to fraggle@gmail.com.
### Reporting bugs
Before reporting a bug, it's worth checking if this really is a bug.
Chocolate Doom's mission is to reproduce the Vanilla (DOS) versions of
the Doom engine games, bugs and all. Check out the
[NOT-BUGS](../NOT-BUGS.md) file for a list of common issues which aren't
really bugs at all. You might also try searching [the GitHub issues
list](https://github.com/chocolate-doom/chocolate-doom/issues) to see
if your bug has already been reported.
If you're confident that you've found a real bug (or even if you're
not sure!) please go ahead and [file an issue on
GitHub](https://github.com/chocolate-doom/chocolate-doom/issues/new).
You'll need a GitHub account, but it's pretty easy to sign up.
Please try to give as much information as possible:
* What version of Chocolate Doom are you using? Check the title bar of
the window for the version number.
* Chocolate Doom runs on many different operating systems (not just
Windows!). Please say which operating system and what version of it
you're using.
* Please say which game you're playing (Doom 1, Doom 2, Heretic,
Hexen, Strife, etc.) and if you're using any fan-made WADs or mods,
please say which mods (and where they can be downloaded!). It helps
to give the full command line you're using to start the game.
* Please mention if you have any special configuration you think may be
relevant, too.
### Feature requests
Chocolate Doom is always open to new feature requests; however, please
be aware that the project is designed around a deliberately limited
[philosophy](../PHILOSOPHY.md), and many features common in other source
ports will not be accepted. Here are a few common requests which are
often rejected:
* "High resolution" rendering (greater than 320x200 display).
* An option to disable Vanilla limits, such as the visplane rendering
limit.
* Ability to play "No Rest For The Living", the expansion pack which
comes with the XBLA / BFG Edition of Doom.
If you're not sure whether your feature is in line with the project
philosophy, don't worry - just ask anyway!
To make a feature request, [file an issue on
GitHub](https://github.com/chocolate-doom/chocolate-doom/issues/new).
### Bug fixes / code submission
Thank you for contributing code to Chocolate Doom! Please check the
following guidelines before opening a pull request:
* All code must be licensed under [the GNU General Public License,
version 2](https://www.gnu.org/licenses/old-licenses/gpl-2.0.en.html).
Please don't reuse code that isn't GPL, or that is GPLv3 licensed.
Be aware that by submitting your code to the project, you're agreeing
to license it under the GPL.
* Please follow the coding style guidelines described in the
[HACKING](../HACKING.md) file.
* Please don't make unnecessary changes which just change formatting
without any actual change to program logic. While being consistent
is nice, such changes destroy the ability to use the `git blame`
command to see when code was last changed.
* The guidelines given above in the "feature requests" section also
apply here. New features which aren't in line with the project
philosophy are likely to be rejected. If you're not sure, open a
feature request first and ask before you start implementing your
feature.
* Follow the guidelines for [how to write a Git commit
message](http://chris.beams.io/posts/git-commit/). In short: the
first line should be a short summary; keep to an 80 column limit;
use the imperative mood ("fix bug X", rather than "fixed bug X" or
"fixing bug X"). If your change fixes a particular subsystem,
prefix the summary with that subsystem: eg. "doom: Fix bug X" or
"textscreen: Change size of X".
* If you're making a change related to a bug, reference the GitHub
issue number in the commit message, eg. "This is a partial fix
for #646". This will link your commit into the issue comments. If
your change is a fix for the bug, put the word "fixes" before the
issue number to automatically close the issue once your change
is merged.

# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, gender identity and expression, level of experience,
nationality, personal appearance, race, religion, or sexual identity and
orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at fraggle@gmail.com. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,

# Coding style guidelines
The coding style guidelines for Chocolate Doom are designed to keep the
style of the original source code. This maintains consistency throughout
the program, and does not require the original code to be changed. Some
of these guidelines are stricter than what was done in the original
source; follow these when writing new code only: there is no need to
change existing code to fit them.
You should set tabs to *display* as eight spaces, not four. However,
*indentation* should be four spaces. If possible, do not use tab
characters at all. There is a utility called “expand” which will remove
tab characters. For the reasoning behind this, see:
http://www.jwz.org/doc/tabs-vs-spaces.html
Please write code to an 80 column limit so that it fits within a standard
80 column terminal. Do not leave trailing whitespace at the end of lines.
Functions should be named like this: `AB_FunctionName`. The `AB` prefix
denotes the subsystem (`AM_` for automap, `G_` for game, etc). If a
function is static, you can omit the prefix and just name it like
`FunctionName`. Functions and global variables should always be made
static if possible.
Put `_t` on the end of types created with typedef. Type names like this
should be all lowercase and have the subsystem name at the start. An
example of this is `txt_window_t`. When creating structures, always
typedef them.
Do not use Hungarian notation.
Do not use the goto statement.
Use C++-style comments, ie. `//` comments, not `/* ... */` comments.
I don’t care that this isn’t standard ANSI C.
Variables should be named like this: `my_variable_name`, not like this:
`MyVariableName`. In pointer variable declarations, place the `*` next
to the variable name, not the type.
When casting variables from one type to another, put a space after the
last closing brace.
When using an if, do, while, or for statement, always use the { } braces
even when they are not necessary. For example, do this:
```c
if (condition)
{
body;
}
```
Not this:
```c
if (condition) // NO
body;
```
Write code like this:
```c
typedef struct
{
int member1;
char *member2;
} my_structure_t;
void FunctionName(int argument, int arg2, int arg3, int arg4, int arg5,
int arg6, int arg7)
{
int assign_var;
assign_var = arg2 + arg3 * arg4 * (arg5 + arg6);
if (foo && !bar || baz && qux || !(foo && bar && baz))
{
body;
}
else if (xyz + 4 < abc * 4 + 3)
{
body;
}
else
{
body;
}
if (very_long_condition_like_this_one_that_forces_a_line_break
&& other_condition)
{
body;
}
switch (argument)
{
case FIRST:
code;
break;
case SECOND:
code;
break;
default:
break;
}
for (a = 0; a < 10; ++a)
{
FunctionCall(arg1, arg2, arg3, arg4,
arg_split_onto_second_line);
}
while (a < 10)
{
loop_body;
}
do
{
} while (condition);
}
```
## Editor-specific default settings
If you use vim, you can put this into your `.vimrc` (or install the
`localvimrc` script):
```
set expandtab
set tabstop=8
set softtabstop=4
set shiftwidth=4
```
Or, if you use Emacs, put this in your `.emacs`:
```lisp
(add-hook 'c-mode-hook (lambda ()
(when (and buffer-file-name
(string-match "chocolate-doom" buffer-file-name))
(c-set-style "bsd")
(setq indent-tabs-mode nil)
(setq tab-width 8)
(setq c-basic-offset 4))))
```
## Security
The C standard library has a number of unsafe functions that should be
avoided when writing code for Chocolate Doom. These are:
Unsafe function | Safer alternative
------------------|------------------------
`gets()` | `fgets(.., stdin)`
`sprintf` | `M_snprintf()`
`snprintf` | `M_snprintf()`
`vsprintf` | `M_vsnprintf()`
`vsnprintf` | `M_vsnprintf()`
`strcpy()` | `M_StringCopy()`
`strncpy()` | `M_StringCopy()`
`strcat()` | `M_StringConcat()`
`strncat()` | `M_StringConcat()`
`strdup()` | `M_StringDuplicate()`
`realloc()` | `I_Realloc()`
Lots of the code includes calls to DEH_String() to simulate string
replacement by the Dehacked tool. Be careful when using Dehacked
replacements of printf format strings. For example, do not do this:
```c
printf(DEH_String("foo %s"), s);
sprintf(mybuf, DEH_String("bar %s"), t);
```
Instead do this:
```c
DEH_printf("foo %s", s);
DEH_snprintf(mybuf, sizeof(mybuf), "bar %s", t);
```
This does the format string replacement safely in a way that checks
the arguments securely.
## Portability
Chocolate Doom is designed to be cross-platform and work on different
Operating Systems and processors. Bear this in mind when writing code.
Do not use the `long` type (its size differs across platforms; use
`int` or `int64_t` depending on which you want).
Use Doom’s byte data type for byte data. `int` is assumed to be a
32-bit integer, and `short` is a 16-bit integer. You can also use the
ISO C99 data types: `intN_t` and `uintN_t` where N is 8, 16, 32, 64.
Be careful with platform dependencies: do not use Windows API
functions, for example. Use SDL where possible.
Preprocessor `#defines` are set that can be used to identify the OS
if necessary: `_WIN32` for Windows and `__MACOSX__` for Mac OS X. Others
are set through SDL. Try to avoid this if possible.
Be careful of endianness! Doom has `SHORT()` and `LONG()` macros that
do endianness conversion. Never assume that integer types have a
particular byte ordering. Similarly, never assume that fields
inside a structure are aligned in a particular way. This is most
relevant when reading or writing data to a file or a network pipe.
For signed integers, you shouldn’t assume that `(i >> n)` is the same as
`(i / (1 << n))`. However, most processors handle bitshifts of signed
integers properly, so it’s not a huge problem.
Due to Microsoft implementation of the Unicode support in C standard
library you should use these wrappers to support non-latin paths and
filenames on Windows.
C library function | Wrapper
-------------------|-------------------
`fopen()` | `M_fopen()`
`remove()` | `M_remove()`
`rename()` | `M_rename()`
`stat()` | `M_stat()`
`mkdir()` | `M_MakeDirectory()`
`getenv()` | `M_getenv()`

The aim of Chocolate Doom is to behave as closely to Vanilla Doom as
possible. As a result, you may experience problems that you would
also experience when using Vanilla Doom. These are not “bugs” as
Chocolate Doom is behaving as intended.
This is not intended to be a comprehensive list of Vanilla Doom bugs.
For more information, consult the “engine bugs” page of the Doom Wiki.
## Game exits after title screen with message about game version
The game may exit after the title screen is shown, with a message like
the following:
Demo is from a different game version!
(read 2, should be 109)
*** You may need to upgrade your version of Doom to v1.9. ***
See: https://www.doomworld.com/classicdoom/info/patches.php
This appears to be v1.0/v1.1/v1.2.
This usually indicates that your IWAD file that you are using to play
the game (usually named doom.wad or doom2.wad) is out of date.
Chocolate Doom only supports versions 1.666 through 1.9.
To fix the problem, you must upgrade your IWAD file, preferably
to 1.9. The URL in the message has downloadable upgrade patches that
you can use to upgrade.
## Game exits in demo loop when playing Final Doom
When playing with the Final Doom IWAD files (tnt.wad, plutonia.wad),
if you leave the game at the title screen to play through the demo
loop, it will eventually exit with the following error message:
W_GetNumForName: demo4 not found!
This is the same behavior as the Vanilla executables that were
bundled with Final Doom. When Ultimate Doom was developed, a fourth
demo was added to the demo loop, and this change was retained in the
Final Doom version of the executable. However, the Final Doom IWADs
do not include a fourth demo, so the game crashes.
An alternate version of Final Doom was included in the Id Anthology
boxed set, and this version of the game fixed this bug. However, this
version also changes the teleport behavior, so the default is to
emulate the most commonly distributed version of the game. To use
the alternate version, run with:
chocolate-doom -gameversion final2
## Game exits when accessing the options menu
The game may exit with the message “Bad V_DrawPatch” when accessing
the options menu, if you have your mouse sensitivity set high.
The Doom options menu has a slider that allows the mouse sensitivity
to be controlled; however, it has only a very limited range. It is
common for experienced players to set a mouse sensitivity that is much
higher than what can be set via the options menu. The setup program
allows a larger range of values to be set.
However, setting very high sensitivity values causes the game to exit
when accessing the options menu under Vanilla Doom. Because Chocolate
Doom aims to emulate Vanilla Doom as closely as possible, it does the
same thing.
One solution to the problem is to set a lower mouse sensitivity.
Alternatively, all of the settings in the options menu can be
controlled through Doom’s key bindings anyway:
Option | Key
---------------------------|-----
End game | F7
Messages on/off | F8
Graphic detail high/low | F5
Screen size smaller/larger | -/+
Sound volume menu | F4
## Game exits with “Savegame buffer overrun” when saving the game
If you are playing on a particularly large level, it is possible that
when you save the game, the game will quit with the message “Savegame
buffer overrun”.
Vanilla Doom has a limited size memory buffer that it uses for saving
games. If you are playing on a large level, the buffer may be too
small for the entire savegame to fit. Chocolate Doom allows the limit
to be disabled: in the setup tool, go to the “compatibility” menu and
disable the “Vanilla savegame limit” option.
If this error happens to you, your game has not been lost! A file
named temp.dsg is saved; rename this to doomsav0.dsg to make it appear
in the first slot in the “load game” menu. (On Unix systems, you will
need to look in the .chocolate-doom/savegames directory in your home
directory)
## Game ends suddenly when recording a demo
If you are recording a very long demo, the game may exit suddenly.
Vanilla Doom has a limited size memory buffer that it uses to save the
demo into. When the buffer is full, the game exits. You can tell if
this happens, as the demo file will be around 131,072 bytes in size.
You can work around this by using the -maxdemo command line parameter
to specify a larger buffer size. Alternatively, the limit can be
disabled: in the setup tool, go to the compatibility menu and disable
the “Vanilla demo limit” option.
## Game exits with a message about “visplanes”
The game may exit with one of these messages:
R_FindPlane: no more visplanes
R_DrawPlanes: visplane overflow (129)
This is known as the “visplane overflow” limit and is one of the most
well-known Vanilla Doom engine limits. You should only ever experience
this when trying to play an add-on level. The level you are trying to
play is too complex; it was most likely designed to work with a limit
removing source port.
More information can be found here (archived link): https://archive.is/s6h7V
## IDMUS## cheat doesn’t work with shareware/registered Doom IWADs
The IDMUS cheat allows the in-game music to be changed. However, in
the original v1.9 this cheat didn’t work properly when playing with
the Doom 1 (shareware and registered) IWADs. This bug was fixed in
the Ultimate Doom and Final Doom executables.
Chocolate Doom emulates this bug. When playing with the shareware or
registered Doom IWADs, the IDMUS cheat therefore does not work
properly. If you are playing with the Ultimate Doom IWAD, the
Ultimate Doom executable is emulated by default, so the cheat works
properly.
## Some graphics are wrong when playing with BFG Edition IWADs
If you are playing using the IWAD files from Doom 3: BFG Edition, you
may notice that certain graphics appear strange or wrong. This
includes the title screen, and parts of the options menu.
The IWAD files in the new BFG Edition have had some significant
changes from the IWAD files in older releases. Some of the graphics
lumps have been removed or changed, and the Doom 2 secret levels are
also censored. Chocolate Doom includes some small workarounds that
allow the game to run, but for the best experience, it’s best to get a
copy of the classic versions of the IWADs. These are still available
to buy from Steam or GOG.com.

@ -1,214 +0,0 @@
Chocolate Doom has been designed around a careful and deliberate
philosophy that attempts to recreate the original (“Vanilla”) DOS
executables for Doom, Heretic, Hexen and Strife. This document
describes some of that philosophy and the reasoning behind it.
This document is descriptive, not proscriptive.
# Vanilla behavior
Ideally Chocolate Doom aims to recreate the behavior of the Vanilla
binaries, but different aspects of Vanilla behavior are held to
varying degrees of importance. It can be imagined as different “tiers”
of compatibility:
* The game and gameplay itself is of central importance. Here, the
Vanilla behavior ought to be maintained as accurately as possible.
This includes the look, feel and sound, and things like demo
compatibility.
* The surrounding aspects of the game that aren’t part of the central
gameplay experience can be extended as long as there’s a good
reason and Vanilla behavior is respected.
* The setup tool is not required to reproduce the behavior of the
Vanilla setup tool, even though it reproduces its look and feel.
“Vanilla” is defined as:
* DOS Doom 1.9 (although there are actually multiple “1.9”s).
* DOS Heretic 1.3.
* DOS Hexen 1.1 (although there are actually two known “1.1”s).
* DOS Strife 1.31.
* DOS Chex Quest.
Compatibility with older versions of the DOS binaries is also a
secondary goal (though not pre-release versions). Other ports (either
official or unofficial) are out of scope: this includes console ports,
non-DOS ports, Doom 95 and Doom 3: BFG Edition.
# Compatibility
Chocolate Doom aims to be compatible with Vanilla Doom in several
different ways. Examples are:
* Bug compatibility: the aim is to emulate compatibility of the
original game down to bugs that were present in the DOS
executables. This includes maintaining the limitations of the
original engine: for example, the infamous “visplane overflow” bug
is intentionally still present, where other source ports have
removed it; this allows mappers targeting Vanilla Doom to use
Chocolate Doom as a faithful substitute.
* Demo compatibility: Doom was one of the first games to develop a
‘speedrunning’ community, and thousands of recordings of Doom
gameplay (`.lmp` demo files) exist in the Compet-N archive. Chocolate
Doom aims for the highest standard of demo compatibility with
Vanilla Doom, a goal that is often complicated by obscure behavior
that can be difficult to reproduce.
* Configuration file compatibility: Chocolate Doom uses the same
configuration file format as Vanilla Doom, such that a user should
be able to reuse their existing Vanilla configuration file without
making any changes. Extra non-Vanilla options are stored in a
separate configuration file.
* Savegame file compatibility: Chocolate Doom uses the same savegame
file format as Vanilla, such that it should be possible to import
and use existing savegame files.
# DOS tools
Chocolate Doom includes some features that aren’t part of Vanilla Doom
but exist for compatibility with DOS tools that interact with it.
These are considered part of the Vanilla experience and ought to be
treated as such. Some examples are:
* The novert setting, which reproduces the functionality of
`novert.exe`.
* The `-deh` parameter, which loads Dehacked patches like dehacked.exe
does under DOS. Chocolate Doom imposes the same limitations that
Vanilla Dehacked does.
# Exceptions
Chocolate Doom differs from Vanilla Doom in a number of ways. In most
cases these are subtle, minor differences. Nonetheless they deserve
some explanation and justification. Here are some examples of
situations where changes are considered acceptable:
1. Vanilla behavior can be broken that is harmful, eg. can damage the
player’s computer, or is just outright misleading. For example:
- Vanilla uses unbounded sprintf and strcpy (security issue).
- Vanilla has crashes that force the user to reboot the machine.
- Vanilla has an out of memory message that recommends tweaking
CONFIG.SYS. As Chocolate Doom doesn’t run under DOS, reproducing
this message would not be helpful.
2. Subtly extending behavior is okay where it’s not clear what the
Vanilla behavior is anyway. For example:
- Opening the menu releases mouse grab in Chocolate Doom.
- Chocolate Hexen’s graphical startup screen runs in a window.
3. Supporting obsolete technology is not a goal: it’s considered
acceptable that Chocolate Doom does not support every type of
hardware from 1993. However, Chocolate Doom should aim to recreate
the functionality in a modern way. Examples of technologies that
aren’t supported are:
- No support for IPX networks, but TCP/IP is supported instead.
- No support for dial-up/serial connections; modern operating
systems have features that do that for you.
- No MS-DOS version.
4. Changes are acceptable that allow the player to be able play the
game. For example:
- There are new key bindings for actions that can’t be rebound with
Vanilla Doom, because it’s useful for portability to machines
that don’t have a full keyboard.
- There are additional mouse and joystick button bindings that let
you perform actions with them that can only be done with the
keyboard in Vanilla Doom.
- Chocolate Doom includes some hacks to support the Doom 3: BFG
Edition IWAD files. The assumption is that being able to at least
play is better than nothing, even if it’s not Vanilla behavior.
- Chocolate Strife does not emulate the save bug from
Vanilla 1.31, which could corrupt saves when overwriting a slot,
if the old slot was not part of the current game’s progression.
Vanilla behavior is unexpected and potentially devastating.
5. Adding extra options to Vanilla functionality is acceptable as long
as the defaults match Vanilla, it doesn’t change gameplay and
there’s a good reason for it. For example:
- PNG screenshots are supported because PCX is an obsolete format.
- Chocolate Doom has the vanilla_keyboard_mapping option that
allows the user to use the native keyboard mapping for their
computer, rather than always assuming a US layout.
6. Changing configuration file defaults is acceptable where there’s a
very good reason. For example:
- Vanilla Doom defaults to no sound or music if a configuration
file is not found. Chocolate Doom defaults to having sound
effects and music turned on by default, because modern computers
support these; there’s no need to configure hardware IRQ settings
to get sound working.
7. Things can be changed if they’re really just inconsequential. For
example:
- The startup messages in Chocolate Doom are not identical to
Vanilla Doom and are not necessarily in the same order.
- Vanilla Doom has command line options named `-comdev`, `-shdev`
and `-regdev` used by id internally for development; these have
been removed.
8. Expansions to the vanilla demo formats are allowed, to make
recording and playback of vanilla gameplay more convenient, with
the following restrictions:
- Such expansions are not supported in WAD files (they are not
an editing feature for WAD authors to use).
- Support for these features can be completely disabled using the
`-strictdemos` command line argument.
- A warning is shown to the user on the console (stdout) when a
demo using one of these features is recorded or played back.
A good litmus test of when it’s acceptable to break from Vanilla
behavior is to ask the question: “Although this is Vanilla behavior,
is there anyone who would want this?”
For example, emulating Vanilla bugs like the visplane overflow bug is
something that is useful for people making Vanilla format maps. On the
other hand, painstakingly emulating Vanilla Doom by starting with no
sound or music by default is not helpful to anyone.
# Minimalism
Chocolate Doom aims to be minimalist and straightforward to configure;
in particular, the setup tool should have a sane interface. Part of
the inspiration for Chocolate Doom came from Boom’s complicated maze
of options menus (and a desire to avoid them). Too many preferences
lead to a bad user interface; see Havoc Pennington’s essay on Free
Software UI:
http://ometer.com/free-software-ui.html
Chocolate Doom has some options that are quite obscure and only really
of interest to a small number of people. In these cases, the options
are hidden away in configuration files and deliberately not exposed in
the setup tool. The assumption is that if you care enough about those
obscure features, editing a configuration file by hand should not be a
huge problem for you.
Also inspirational was the README file from Havoc’s Metacity window
manager, where the list of features begins:
> Boring window manager for the adult in you. Many window managers
> are like Marshmallow Froot Loops; Metacity is like Cheerios.
I’d like to think that Chocolate Doom’s philosophy towards features is
similar. The idea is for a source port that is boring. I find the best
software - both proprietary and open source - is software that is
“egoless”: it does a job well without pretentions about its importance
or delusions of grandeur. A couple of other notable examples of
software that I feel embody this spirit of design in a beautiful way
are Marco Pesenti Gritti’s Epiphany web browser and Evince PDF viewer.
# Other philosophical aspects
Chocolate Doom aims for maximal portability. That includes running on
many different CPUs, different operating systems and different devices
(ie. not just a desktop machine with a keyboard and mouse).
Chocolate Doom is and will always remain Free Software. It will never
include code that is not compatible with the GNU GPL.

Doom has a memorable and atmospheric soundtrack. Like many games of
the era, it is MIDI-based. Chocolate Doom includes a number of
different options for music playback, detailed below.
# Native MIDI playback
Most modern operating systems have some kind of built-in support for
MIDI playback; some have very good quality MIDI playback (Mac OS X for
example). To use this, choose “Native MIDI” in the sound configuration
dialog in the setup tool.
# Timidity
Timidity is a software-based MIDI synthesizer, and a version of it is
included in the SDL2_mixer library used by Chocolate Doom. To use
Timidity for MIDI playback, first download a sound font. An example of
a good quality sound font is the eawpats font, which can be downloaded
from the idgames archive as sounds/eawpats.zip:
https://www.doomworld.com/idgames/sounds/eawpats
Having installed a sound font, select “Native MIDI” in the sound
configuration dialog in the setup tool, and use the “Timidity
configuration file” widget below to enter the path to the Timidity
configuration file (normally named timidity.cfg).
# Gravis Ultrasound (GUS)
The Gravis Ultrasound (GUS) was a PC sound card popular in the ’90s,
notable for having wavetable synthesis that provided MIDI playback
that was superior to most other cards of the era. Chocolate Doom
includes a “pseudo-GUS emulation” feature that simulates the GUS
(using Timidity, under the hood).
To use this feature you need a copy of the GUS patch files that were
distributed with the original GUS patches. If you have Doom 3: BFG
Edition, these patches are included with its version of classic Doom,
and are automatically detected. Otherwise, they can be downloaded
from the idgames archive as music/dgguspat.zip:
https://www.doomworld.com/idgames/music/dgguspat
Having downloaded the patches, select “GUS (emulated)” in the sound
configuration dialog in the setup tool, and use the “GUS patch path”
widget to enter the path to the directory containing the patch files.
For the music not to sound weird, you will almost certainly want to
load gusgonna.wad (sounds/gusgonna.zip in the idgames archive) when
you run the game, to work around a bug in vanilla Doom's instrument
mappings parser:
https://www.doomworld.com/idgames/sounds/gusgonna
By default a GUS card with 1024KB is simulated; to simulate a 256KB,
512KB or 768KB card instead, change the gus_ram_kb option in
chocolate-doom.cfg.
# OPL (Soundblaster / Adlib)
Most people playing Doom in the ’90s had Soundblaster-compatible sound
cards, which used the Yamaha OPL series of chips for FM-based MIDI
synthesis. Chocolate Doom includes the ability to emulate these chips
for a retro experience. OPL emulation is the default MIDI playback,
but can be selected in the setup tool as “OPL (Adlib/SB)”.
Most modern computers do not include an OPL chip any more, as CPUs are
fast enough to do decent software MIDI synthesis. However, no software
emulator sounds exactly like a real (hardware) OPL chip, and a few
cards do have real hardware OPL. If you have such a card, here’s how
to configure Chocolate Doom to use it.
## Sound cards with OPL chips
If you have an ISA sound card, it almost certainly includes an OPL
chip. Modern computers don’t have slots for ISA cards though, so you
must be running a pretty old machine.
If you have a PCI sound card, you probably don’t have an OPL chip.
However, there are some exceptions to this. The following cards are
known to include “legacy” OPL support:
* C-Media CMI8738 (*)
* Forte Media FM801
* Cards based on the Yamaha YMF724 (*)
Other cards that apparently have OPL support but have not been tested:
* S3 SonicVibes
* AZTech PCI 168 (AZT 3328 chipset)
* ESS Solo-1 sound cards (ES1938, ES1946, ES1969 chipset)
* Conexant Riptide Audio/Modem combo cards
* Cards based on the Crystal Semiconductors CS4281
* Cards based on the Avance Logic ALS300
* Cards based on the Avance Logic ALS4000
If you desperately want hardware OPL music, you may be able to find
one of these cards for sale cheap on eBay.
For the cards listed above with (\*) next to them, OPL support is
disabled by default and must be explictly enabled in software. See
sections below for operating system-specific instructions on how you
may be able to do this.
If your machine is not a PC, you don’t have an OPL chip, and you will
have to use the software OPL.
## Operating System support
If you’re certain that you have a sound card with hardware OPL, you
may need to take extra steps to configure your operating system to
allow access to it. To do hardware OPL, Chocolate Doom must access
the chip directly, which is usually not possible in modern operating
systems unless you are running as the superuser (root/Administrator).
### Microsoft Windows
On modern Windows systems it is not possible to directly access the
OPL chip, even when running as Administrator. Fortunately, it is
possible to use the “ioperm.sys” driver developed for Cygwin (look for
iopermsys-0.2.1.tar.bz2):
http://openwince.sourceforge.net/ioperm/
It is not necessary to have Cygwin installed to use this. Copy the
ioperm.sys file into the same directory as the Chocolate Doom
executable and it should be automatically loaded.
You can confirm that hardware OPL is working by checking for this
message in stdout.txt:
OPL_Init: Using driver 'Win32'.
If you have a C-Media CMI8738, you may need to enable the `FM_EN`
flag in Windows Device Manager to access hardware OPL output. See
[this](http://www.vogons.org/viewtopic.php?f=46&t=36445) thread on
vogons.org for some more information.
### Linux
If you are using a system based on the Linux kernel, you can access
the OPL chip directly, but you must be running as root. You can
confirm that hardware OPL is working, by checking for this message on
startup:
OPL_Init: Using driver 'Linux'.
If you are using one of the PCI cards in the list above with a (*)
next to it, you may need to manually enable FM legacy support. Add
the following to your /etc/modprobe.conf file to do this:
options snd-ymfpci fm_port=0x388
options snd-cmipci fm_port=0x388
### OpenBSD/NetBSD
You must be running as root to access the hardware OPL directly. You
can confirm that hardware OPL is working by checking for this message
on startup:
OPL_Init: Using driver 'OpenBSD'.
There is no native OPL backend for FreeBSD yet. Sorry!
# Other options
If you have some other favorite MIDI playback option that isn’t
listed above, you can set a hook to invoke an external command for
MIDI playback using the ‘snd_musiccmd’ configuration file option. For
example, set:
snd_musiccmd "aplaymidi -p 128:0"
in your chocolate-doom.cfg file.

## What is it?
Chocolate Strife is the most accurate and complete recreation of Rogue
Entertainment’s “Strife: Quest for the Sigil.” It was created through more
than four years of reverse engineering effort with the blessings of the
original programmers of the game.
## Why?
The source code for Strife was lost, which means, unlike the code for all the
other commercial DOOM-engine games, it cannot be released. The only access we
have to the code is the binary executable file. Tools such as IDA Pro have
been employed to disassemble and decompile the executable, which was cross-
referenced against the Linux DOOM and DOS Heretic sources and painstakingly
combed over multiple times, instruction-by-instruction, to ensure that the
resulting Chocolate Doom-based executable is as close as possible to the
original.
## Is it Legal?
Chocolate Strife was originally reverse-engineered from the DOS Strife
binaries. Although reverse engineering is legally a protected activity, this
nonetheless left some open questions about its legal status.
In 2014, a new commercial release of Strife was published (Strife: Veteran
Edition) based on the Chocolate Strife code, and developed by the authors of
Chocolate Strife under commercial license. The release of Strife: Veteran
Edition, along with its GPL-licensed source code, constitutes tacit approval
for the legal status of Chocolate Strife by its current copyright holder.
## Is it Perfect?
Almost, but not entirely! That’s where you come in. Help us by reporting any
discrepancies you may notice between this executable and the vanilla DOS
program!
However, do *not* report any glitch that you can replicate in the vanilla EXE
as a bug. The point of Chocolate Strife, like Chocolate Doom before it, is to
be as bug-compatible with the original game as possible. Also be aware that
some glitches are impossible to compatibly recreate, and wherever this is the
case, Chocolate Strife has erred on the side of not crashing the program,
for example by initializing pointers to NULL rather than using them without
setting a value first.
## What are some known problems?
The demo version is *not* supported, and there are not any current plans to
support it in the future, due to the vast number of differences (the demo
version of Strife is based on an earlier version of Rogue’s
codebase).
The commercial Strife IWAD version 1.1 may run, but also exhibit issues. Like
the demo version, there are no current plans to fully support it. Make sure
your copy is updated to at least 1.2. Strife: Veteran Edition already
includes the required version.
## How do I use it?
From the Run box or a command line, issue a command to Chocolate Strife just
like you would run Chocolate Doom. Most of the same command line parameters
are supported.
voices.wad will be read from the same directory as the IWAD, if it can be
found. If it is not found, then voices will be disabled just as would happen
with the vanilla executable. Do not add voices.wad using -file, as that is
redundant and unnecessary.
Some new command-line parameters in Chocolate Strife include the following:
- -nograph
- Disables the graphical introduction sequence. -devparm implies this.
- -novoice
- Disables voices even if voices.wad can be found.
- -work
- Enables Rogue’s playtesting mode. Automatic godmode, and pressing the
inventory drop key will toggle noclipping.
- -flip
- Flips player gun graphics. This is buggy, however, because it does not
reverse the graphics’ x offsets (this is an accurate emulation of the
vanilla engine’s behavior).
- -random
- Randomizes the timing and location of item respawns in deathmatch, when
item respawning is enabled.

# Chocolate Doom
Chocolate Doom aims to accurately reproduce the original DOS version of
Doom and other games based on the Doom engine in a form that can be
run on modern computers.
Originally, Chocolate Doom was only a Doom source port. The project
now includes ports of Heretic and Hexen, and Strife.
Chocolate Doom’s aims are:
* To always be 100% Free and Open Source software.
* Portability to as many different operating systems as possible.
* Accurate reproduction of the original DOS versions of the games,
including bugs.
* Compatibility with the DOS demo, configuration and savegame files.
* To provide an accurate retro “feel” (display and input should
behave the same).
More information about the philosophy and design behind Chocolate Doom
can be found in the PHILOSOPHY file distributed with the source code.
## Setting up gameplay
For instructions on how to set up Chocolate Doom for play, see the
INSTALL file.
## Configuration File
Chocolate Doom is compatible with the DOS Doom configuration file
(normally named `default.cfg`). Existing configuration files for DOS
Doom should therefore simply work out of the box. However, Chocolate
Doom also provides some extra settings. These are stored in a
separate file named `chocolate-doom.cfg`.
The configuration can be edited using the chocolate-setup tool.
## Command line options
Chocolate Doom supports a number of command line parameters, including
some extras that were not originally suported by the DOS versions. For
binary distributions, see the CMDLINE file included with your
download; more information is also available on the Chocolate Doom
website.
## Playing TCs
With Vanilla Doom there is no way to include sprites in PWAD files.
Chocolate Doom’s ‘-file’ command line option behaves exactly the same
as Vanilla Doom, and trying to play TCs by adding the WAD files using
‘-file’ will not work.
Many Total Conversions (TCs) are distributed as a PWAD file which must
be merged into the main IWAD. Typically a copy of DEUSF.EXE is
included which performs this merge. Chocolate Doom includes a new
option, ‘-merge’, which will simulate this merge. Essentially, the
WAD directory is merged in memory, removing the need to modify the
IWAD on disk.
To play TCs using Chocolate Doom, run like this:
```
chocolate-doom -merge thetc.wad
```
Here are some examples:
```
chocolate-doom -merge batman.wad -deh batman.deh vbatman.deh (Batman Doom)
chocolate-doom -merge aoddoom1.wad -deh aoddoom1.deh (Army of Darkness Doom)
```
## Other information
* Chocolate Doom includes a number of different options for music
playback. See the README.Music file for more details.
* More information, including information about how to play various
classic TCs, is available on the Chocolate Doom website:
https://www.chocolate-doom.org/
You are encouraged to sign up and contribute any useful information
you may have regarding the port!
* Chocolate Doom is not perfect. Although it aims to accurately
emulate and reproduce the DOS executables, some behavior can be very
difficult to reproduce. Because of the nature of the project, you
may also encounter Vanilla Doom bugs; these are intentionally
present; see the NOT-BUGS file for more information.
New bug reports, feedback, questions or suggestions can be submitted
to the issue tracker on Github:
https://github.com/chocolate-doom/chocolate-doom/issues
* Source code patches are welcome, but please follow the style
guidelines - see the file named HACKING included with the source
distribution.
* Chocolate Doom is distributed under the GNU GPL. See the COPYING
file for more information.

This is Chocolate Doom’s “to do” list. Note that this is kind of an arbitrary
and unstructured wish list of features and improvements. The bug tracker
(http://chocolate-doom.org/bugs) has more feature requests.
* Multiplayer:
- Use UPnP to automatically configure port forwarding for NATed
networks.
- Multiplayer options and configuration file (server name, etc)
* Improve multiplayer startup:
- Select an IWAD automatically from the server’s game type rather than
all players having to specify -iwad.
- Send list of WADs to load instead of all clients having to specify -file.
- Same applies to dehacked patches and wad merging parameters.
* Portability improvements:
- Test on and fix for architectures where `((-2) >> 1) != -1`
- Use size-specific types (eg. `int32_t` instead of int)
- Don’t make structure packing assumptions when loading levels.
- Port to every OS and architecture under the sun
- Port to Emscripten and release a web-based version.
* Video capture mode
- Real-time recording of gameplay
- Batch conversion of demos into videos
* Heretic/Hexen/Strife:
- Merge r_draw.c to common version and delete duplicates
- Heretic v1.2 emulation (if possible)
- Hexen v1.0 emulation (if possible/necessary)
- Strife v1.1 emulation (for demo IWAD support)
- Screensaver mode
Crazy pie in the sky ideas:
* Automatic WAD installer - download and run TCs from a list automatically
(automating the current “instructions on wiki” system).
* Textscreen interface to the Compet-N database: menu driven system to
automatically download and play speedruns.
* DWANGO-like interface for finding players and setting up games.

The Chocolate Doom icon is based on an image by Chris Metcalf
(http://www.chrismetcalf.org/) which is copyrighted to him:
http://www.flickr.com/photos/laffy4k/448920776/
Chris has kindly agreed that the Chocolate Doom icon may be used under
the GNU GPL, so the copyright status of the icon is the same as that of
the rest of the project.
The "foo8.ico" files are 8-bit depth only, while the "foo.ico" files
contain full 32-bit versions, scaled to different sizes and with proper
alpha masks (as well as the 8-bit versions). The 8-bit versions are
used when setting the icon within SDL, as SDL under Windows displays
full color icons in a very poor quality. The full-color versions are
used in the resource files.

# LONG_GAME_NAME installation
These are instructions for how to install and set up LONG_GAME_NAME
for play.
#if !PRECOMPILED
# Building LONG_GAME_NAME
Before you can play LONG_GAME_NAME, you need to compile a binary that
you can run. For compilation, LONG_GAME_NAME requires the following
to be installed:
* A C compiler (gcc is recommended)
* make (GNU make is recommended)
* SDL2 (see https://www.libsdl.org/)
* SDL2_mixer (see https://www.libsdl.org/projects/SDL_mixer/)
* SDL2_net (see https://www.libsdl.org/projects/SDL_net/)
* Python (optional)
Follow the standard instructions for installing an autotools-based
package:
1. Run `./configure` to initialize the package.
2. Run `make` to compile the package.
3. Run `make install` to install the package.
An automated build script is available that installs the necessary
dependencies and builds the source code automatically. See the build
instructions on the website.
Advanced topics such as cross-compilation are beyond the scope of this
document. Please see the GNU autoconf / automake documentation for more
information.
#endif
# Obtaining an IWAD file
To play, you need an IWAD file. This file contains the game data
(graphics, sounds, etc). The full versions of the games are
proprietary and need to be bought. The IWAD file has one of the
following names:
| IWAD | Game |
| -------------------------- | ------------------------------- |
#if DOOM
| doom1.wad | Shareware Doom |
| doom.wad | Registered / Ultimate Doom |
| doom2.wad | Doom 2 |
| tnt.wad | Final Doom: TNT: Evilution |
| plutonia.wad | Final Doom: Plutonia Experiment |
| chex.wad | Chex Quest |
| freedoom1.wad | Freedoom: Phase 1 |
| freedoom2.wad | Freedoom: Phase 2 |
| freedm.wad | FreeDM |
#endif
#if HERETIC
| heretic1.wad | Shareware Heretic |
| heretic.wad | Registered / Commercial Heretic |
#endif
#if HEXEN
| hexen.wad | Hexen |
#endif
#if STRIFE
| strife1.wad (+voices.wad) | Strife |
#endif
#if DOOM
If you don’t have a copy of a commercial version, you can download
the shareware version of Doom (extract the file named doom1.wad):
* https://www.doomworld.com/idgames/idstuff/doom/win95/doom95
(idstuff/doom/win95/doom95.zip in your nearest /idgames mirror)
#endif
If you have a commercial version on a CD-ROM, obtaining the IWAD
file is usually straightforward. Simply locate the IWAD file on the
disc and copy it off.
#if !__MACOSX__
#if DOOM
The Doom games are available to purchase for download on Steam
(https://store.steampowered.com/), all releases containing the classic
games including Doom 3: BFG Edition are supported.
#endif
#if HERETIC
Heretic is available to purchase for download on Steam
(https://store.steampowered.com/).
#endif
#if HEXEN
Hexen and its expansion pack are available to purchase for download on
Steam (https://store.steampowered.com/).
#endif
#if STRIFE
Strife: Veteran Edition is available to purchase for download on Steam
(https://store.steampowered.com/).
#endif
#if !_WIN32
For Steam on Linux, you need to enable “Steam Play” for all titles in
order to install the games. You may do this from the Steam menu,
Setup, and the Steam Play tab.
#endif
LONG_GAME_NAME will autodetect IWADs installed by Steam and you do not
need to do anything.
#else
The Doom, Heretic, Hexen, and Strife games are available to purchase
for download on Steam (https://store.steampowered.com/), but are only
available for Windows. To find the IWAD files on a Windows or Wine
system, look in the Steam directory (usually within “Program Files”),
under the “steamapps/common” path.
#endif
#if DOOM || STRIFE
The Doom and Strife: Veteran Edition games are available for purchase
on GOG.com (https://www.gog.com/).
#if _WIN32
LONG_GAME_NAME will autodetect IWADs from the standalone or GOG Galaxy
installers and you do not need to do anything.
#else
The games are only available for Windows, but you may find the IWAD
files on a Windows or Wine system, typically within the “C:\GOG Games”
or “C:\Program Files\GOG Galaxy” directories.
#endif
#endif
#if DOOM || HERETIC
Older floppy disk versions are harder to deal with. The easiest way
to install from floppies is to run the original installer program
inside an emulator such as DOSbox (https://www.dosbox.com/).
As an alternative to using an emulator, it is possible to extract the
files manually. On the install disk(s), you will find several files
with numbered extensions (eg. “doom_se.1”).
From the command line it is possible to combine these files into a
single large file, using a command similar to the following:
#if _WIN32
copy doom_se.1+doom_se.2+doom_se.3+doom_se.4+doom_se.5 doom_se.lzh
#else
cat doom_se.1 doom_se.2 doom_se.3 doom_se.4 doom_se.5 > doom_se.lzh
#endif
The resulting file is an LHA archive file, and it can be extracted
using an LHA archive tool (there is one available for almost every
operating system).
#endif
# Running the game
#if __MACOSX__
Once you have an IWAD file, you can specify its location within the
graphical launcher program. Click the “Configure...” button, and then
click “Set...” for each IWAD to choose its location. From the main
launcher dialog you can then choose which game you want to play and
click the “Launch” button to start the game.
If you are an advanced user and like to run Doom from the command
line, you can use the “Command Prompt...” menu item to open a Terminal
window. The DOOMWADPATH environment variable is preconfigured
to point to the locations of the IWAD files set within the launcher.
You can launch the game with a specific IWAD file by typing, for
example:
LONG_EXE_NAME -iwad tnt.wad
#else
LONG_GAME_NAME needs to know where to find your IWAD file. To do this,
do one of the following:
#if _WIN32
* Within Explorer, simply place the IWAD file in the same folder as
the LONG_GAME_NAME files, and double-click `LONG_EXE_NAME.exe`.
* Run LONG_GAME_NAME from the command prompt with the `-iwad` command
line parameter to specify the IWAD file to use, eg.
LONG_EXE_NAME -iwad c:\games\DEFAULT_IWAD
* Set the environment variable DOOMWADDIR to the location of a
directory containing your IWAD files.
* If you have multiple IWADs in different directories, set the
environment variable DOOMWADPATH to be a semicolon-separated list
of directories to search (similar to the PATH environment
variable).
#else
* Run LONG_GAME_NAME from the Unix console with the `-iwad` command
line parameter to specify the IWAD file to use, eg.
LONG_EXE_NAME -iwad /root/DEFAULT_IWAD
* Put the file into one of the following directories:
$HOME/.local/share/games/doom
/usr/share/doom
/usr/share/games/doom
/usr/local/share/doom
/usr/local/share/games/doom
* Set the environment variable DOOMWADDIR to specify the path to a
directory containing your IWAD files.
* If you have multiple IWADs in different directories, set the
environment variable DOOMWADPATH to be a colon-separated list of
directories to search (similar to the Unix PATH environment
variable).
#endif
#endif
#if DOOM
# Playing with Freedoom
Freedoom is an open content project to create a Doom engine-based game
that is entirely free software. The website can be found here:
https://freedoom.github.io/
Check out the [Chocolate Doom wiki’s page on
Freedoom](https://www.chocolate-doom.org/wiki/index.php/Freedoom)
for more information.
# Playing with Chex Quest
Chex Quest is a game based on Doom with some minor modifications that
was distributed with boxes of Chex cereal in 1997. It is possible to
play Chex Quest using LONG_GAME_NAME. To do this, the following files
are needed:
* The IWAD file “chex.wad”, from the Chex Quest CD.
* The dehacked patch “chex.deh”, which can be found here:
https://www.doomworld.com/idgames/themes/chex/chexdeh
(themes/chex/chexdeh.zip in your nearest /idgames mirror)
Copy these files into a directory together and use the `-iwad` command
line parameter to specify the Chex Quest IWAD file:
LONG_EXE_NAME -iwad chex.wad
#endif
# Installing upgrades
#if DOOM
LONG_GAME_NAME requires a version 1.9 IWAD file. Generally, if you
install a recent version of Doom you should have a version 1.9 IWAD.
#elif HERETIC
LONG_GAME_NAME requires a version 1.2 (Shareware) or version 1.3
(Shadow of the Serpent Riders) IWAD file. Generally, if you install a
recent version of Heretic you should have a version 1.2 or 1.3 IWAD.
#elif HEXEN
LONG_GAME_NAME requires a version 1.1 IWAD file. Generally, if you
install a recent version of Hexen you should have a version 1.1 IWAD.
#elif STRIFE
LONG_GAME_NAME requires a version 1.2 IWAD file. Generally, if you
install a recent version of Strife you should have a version 1.2 IWAD.
Please note that Strife version 1.3 does not update the IWAD, if your
version.txt file says “STRIFE(TM) VERSION 1.3”, you are still good.
#endif
However, if you are installing from a very old CD version or from
floppy disks, you might find you have an older version.
The most obvious symptom of an out of date IWAD file is that the game
will exit at the title screen before the demo starts, with the message
“Demo is from a different game version!”. If this happens, your IWAD
file is out of date and you need to upgrade.
Upgrade patches are available that will update your game to the latest
version, the following sites have the patches:
#if DOOM
* http://www.doom2.net/doom2/utils.html
* http://www.gamers.org/pub/idgames/idstuff/doom
* http://www.gamers.org/pub/idgames/idstuff/doom2
#elif HERETIC
* http://www.gamers.org/pub/idgames/idstuff/heretic
#elif HEXEN
* http://www.gamers.org/pub/idgames/idstuff/hexen
#elif STRIFE
* http://www.gamers.org/pub/idgames/roguestuff
#endif
Please see the
[Doom Wiki’s page on game patches](https://doomwiki.org/wiki/Game_patch)
for more information.
#if _WIN32
As the patches are binary patches that run as DOS executables, on
recent 64-bit versions of Windows you will need to use a DOS emulator
(such as DOSBox) to run them.
#else
As the patches are binary patches that run as DOS executables, you
will need to use a DOS emulator (such as DOSBox) to run them.
#endif
# Music support
LONG_GAME_NAME includes OPL emulation code that accurately reproduces
the way that the in-game music sounded under DOS when using an
Adlib/Soundblaster card. This is, however, not to everyone’s taste.
LONG_GAME_NAME includes a number of different options for better
quality MIDI playback; see the file README.Music for more details of
how to set these up.
#if !PRECOMPILED
When compiling from source, be sure to compile and install Timidity
before installing SDL2_mixer.

.TH @CFGFILE@ 5 2017-11-30 "@PACKAGE_NAME@ @VERSION@"
.SH NAME
@CFGFILE@ \- @PACKAGE_SHORTNAME@ @GAME_UPPER@ configuration file
.SH DESCRIPTION
.PP
\fI@CFGFILE@\fR
is the configuration file for \fB@PROGRAM_SPREFIX@\-@GAME@\fR(6). The configuration
options stored in the file are the same as those stored in the
original DOS Vanilla @GAME_UPPER@.
Extra @PACKAGE_SHORTNAME@ @GAME_UPPER@-specific options are stored in a separate
configuration file, \fB@PROGRAM_SPREFIX@\-@GAME@.cfg\fR.
.PP
\fI@CFGFILE@\fR is normally stored in the user's home directory,
as \fI~/.local/share/@PROGRAM_SPREFIX@\-@GAME@/@CFGFILE@\fR. The path can be
overridden using the \fBXDG_DATA_HOME\fR environment variable (see the XDG
Base Directory Specification).
.PP
The \fB@PROGRAM_SPREFIX@\-@GAME@\-setup\fR(6) tool provides a simple to use front-end
for editing \fI@CFGFILE@\fR.
.SH FILE FORMAT
The file is a plain-text file, consisting of a list of configuration
options and their values, separated by whitespace. Each option is stored
on a separate line. Options have different types; an option may have
either an integer, floating point or string value. If the option is
of a string type, the value is surrounded by quotes (").
.PP
For example:
.RS
.PP
.EX
integer_value 1
integer_value2 1
floating_point_value 4.2
string_value "hello world"
.EE
.RE
.PP
Invalid lines or comments in the file will be ignored, but it is advisable
not to put them in the file; the file is rewritten from scratch every time
the game exits, so any invalid lines or comments will be lost.
.PP
Some options are used for keyboard key bindings; these are stored as
integer values containing the keyboard scan code of the key to be bound to.
Boolean values are also stored as integers, with a value of zero usually
indicating "false" and a non-zero value indicating "true".

.I PCSOUND_DRIVER
When running in PC speaker sound effect mode, this environment variable
specifies a PC speaker driver to use for sound effect playback.
Valid options are
.RB \(lq Linux \(rq

.RB \(lq BSD \(rq
for the NetBSD/OpenBSD PC speaker driver,
and
.RB \(lq SDL \(rq
for SDL-based emulated PC speaker playback (using the digital output).

When using OPL MIDI playback, this environment variable specifies an
OPL backend driver to use.
Valid options are
.RB \(lq SDL \(rq
for an SDL-based software emulated OPL chip,
.RB \(lq Linux \(rq
for the Linux hardware OPL driver,
and
.RB \(lq OpenBSD \(rq
for the OpenBSD/NetBSD hardware OPL driver.
.IP
Generally speaking, a real hardware OPL chip sounds better than software
emulation; however, modern machines do not often include one.
If present, it may still require extra work to set up and elevated
security privileges to access.

To play, an IWAD file is needed.
This is a large file containing all of the levels, graphics,
sound effects, music and other material that make up the game.
IWAD files are named according to the game; the standard names are:
.TP
.IR doom.wad ,\~\c
.IR doom1.wad ,\~\c
.IR doom2.wad ,\~\c
.IR tnt.wad ,\~\c
.I plutonia.wad
Doom, Doom II, Final Doom
.TP
.IR heretic.wad ,\~\c
.IR hexen.wad ,\~\c
.I strife.wad
Heretic, Hexen and Strife (commercial Doom engine games).
.TP
.IR hacx.wad ,\~\c
.I chex.wad
Hacx and Chex Quest - more obscure games based on the Doom engine.
.TP
.IR freedm.wad ,\~\c
.IR freedoom1.wad ,\~\c
.I freedoom2.wad
The Freedoom open content IWAD files.
.LP
The following directory paths are searched in order to find an IWAD:
.TP
Current working directory
Any IWAD files found in the current working directory will be used in
preference to IWADs found in any other directories.
.TP
.I DOOMWADDIR
This environment variable can be set to contain a path to a single
directory in which to look for IWAD files.
This environment variable is supported by most Doom source ports.
.TP
.I DOOMWADPATH
This environment variable, if set, can contain a colon-separated list of
directories in which to look for IWAD files, or alternatively full paths to
specific IWAD files.
.TP
.I $HOME/.local/share/games/doom
Writeable directory in the user's home directory.
The path can be overridden using the
.I \%XDG_DATA_HOME
environment variable (see the XDG Base Directory Specification).
.TP
.I /usr/local/share/doom
.TQ
.I /usr/local/share/games/doom
.TQ
.I /usr/share/doom
.TQ
.I /usr/share/games/doom
System-wide locations that can be accessed by all users.
The path
.I /usr/share/games/doom
is a standard path that is supported by most Doom source ports.
These paths can be overridden using the
.I \%XDG_DATA_DIRS
environment variable (see the XDG Base Directory Specification).
.LP
The above can be overridden on a one-time basis by using the
.B \-iwad
command line parameter to provide the path to an IWAD file to use.This
parameter can also be used to specify the name of a particular IWAD to use
from one of the above paths.
For example,
.RB \(lq "\-iwad doom.wad" \(rq
will search the above paths for the file
.I doom.wad
to use.

.SH DESCRIPTION
.PP
@PACKAGE_NAME@ is a modern Doom engine designed to behave
as similarly to the original Doom game as is possible.
.PP
.I \%@PROGRAM_SPREFIX@\-server
is a dedicated server for @PACKAGE_SHORTNAME@.
It is equivalent to running
\fB@PROGRAM_SPREFIX@-doom\fR(6)
with the
.B \%\-dedicated
option.
.PP
Game options are not specified to the server, which merely acts to
retransmit data between players in the game; parameters for the
game should be specified by the first player to connect to the server,
who is designated the controlling player.
.SH OPTIONS
.TP
.B \-ignoreversion
Ignore version mismatches between the server and the client.
Using this option may cause game desyncs to occur,
or differences in protocol may mean the netgame will simply not function
at all.
.TP
.BI \-port\~ n
Use UDP port
.I n
for communications instead of the default (2342).
.TP
.B \-privateserver
Don't register with the global master server.
.TP
.BI \-servername\~ name
Specify a name for the server.

.TH @PROGRAM_SPREFIX@\-strife 6 2018-01-15 "@PACKAGE_NAME@ @VERSION@"
.SH NAME
@PROGRAM_SPREFIX@\-strife \- historically compatible Strife engine
.SH SYNOPSIS
.B @PROGRAM_SPREFIX@\-strife
.RI [ options ]
.SH DESCRIPTION
.PP
@PACKAGE_SHORTNAME@ Strife is an accurate and complete recreation of
Rogue Entertainment's
.IR "Strife: Quest for the Sigil" .
It was created through
more than two years of reverse engineering effort with the blessings
of the original programmers of the game;
see section \(lqHISTORY\(rq below.
@content
.SH IWAD SEARCH PATHS
@include iwad_paths.man
.SH ENVIRONMENT
This section describes environment variables that control
@PACKAGE_SHORTNAME@ Strife's behavior.
@include environ.man
.SH FILES
.TP
.I $HOME/.local/share/@PROGRAM_SPREFIX@\-doom/strife.cfg
The main configuration file for @PACKAGE_SHORTNAME@ Strife.
See \fBstrife.cfg\fR(5).
.TP
.I $HOME/.local/share/@PROGRAM_SPREFIX@\-doom/@PROGRAM_SPREFIX@\-strife.cfg
Extra configuration values that are specific to @PACKAGE_SHORTNAME@
Strife and not present in Vanilla Strife.
See \fB@PROGRAM_SPREFIX@\-strife.cfg\fR(5).
.SH SEE ALSO
\fB@PROGRAM_SPREFIX@\-doom\fR(6),
\fB@PROGRAM_SPREFIX@\-server\fR(6),
\fB@PROGRAM_SPREFIX@\-setup\fR(6)
.SH HISTORY
The source code for Strife was lost, which means, unlike the code for
all the other commercial games using the Doom engine, it cannot be
released.
The only access we have to the code is the binary executable file.
Reverse engineering tools were employed to disassemble and decompile the
executables, which were cross-referenced against the Linux Doom and
DOS Heretic sources and painstakingly combed over multiple times,
instruction by instruction, to ensure that the resulting
Chocolate-Doom-based executable is as close as possible to the original.
.SH LEGALITY
Reverse engineering is a protected activity so long as the original code
is not used directly in the product.
Due to the vast amount of information lost through the process of
compilation, and the need to refactor large portions of code in order to
eliminate non-portable idioms or to adapt them properly to Chocolate
Doom's framework, the resulting code behaves the same, but is not the
.I same
code.
.PP
In addition, James Monroe and John Carmack have both stated that they
have no objections to the project.
Because they are the original authors of the code, and neither Rogue nor
their publisher, Velocity, Inc., exist any longer as legal entities,
this is effectively legal permission.
.SH BUGS
@PACKAGE_SHORTNAME@ Strife is almost, but not entirely perfect, in
recreating the behavior of Vanilla Strife.
Help us by reporting any discrepancies you might notice between this
executable and the vanilla DOS program.
.PP
However, do
.I not
report any glitch that you can replicate in the vanilla EXE as a bug.
The point of @PACKAGE_SHORTNAME@ Strife, like Chocolate Doom before it,
is to be as bug-compatible with the original game as possible.
Also be aware that some glitches are impossible to compatibly recreate,
and wherever this is the case, @PACKAGE_SHORTNAME@ Strife has erred on
the side of not crashing the program, for example by initializing
pointers to
.I NULL
rather than using them without setting a value first.
.SH AUTHORS
Chocolate Strife is part of the Chocolate Doom project.
It was reverse engineered from the DOS versions of Strife by James Haley
and Samuel Villarreal.
Chocolate Doom was written and maintained by Simon Howard, and is based
on the LinuxDoom source code released by Id Software.
