Runs NXDoom on the board's LCD, played with a USB HID keyboard and reading the game data from the microSD card, so it exercises the LTDC framebuffer, the OTG FS host and the SDMMC peripheral at once. Three settings are needed that are not obvious: CONFIG_FAT_FORCE_INDIRECT, because the FAT layer otherwise reads whole sectors straight into the caller's buffer and the SDMMC IDMA cannot reach the caller's buffer when it lives in external SDRAM. The failure appears part way through startup, once the internal RAM has filled and allocations start coming from SDRAM. CONFIG_HIDKBD_NOGETREPORT, because the keyboard answers GET_REPORT on the control pipe with an empty report and only delivers key data on its interrupt endpoint. Without it the keyboard enumerates, reports no error, and no key is ever seen. CONFIG_STM32_LTDC_L1_L8 with the frame buffer colour map, because DOOM is natively palettised: letting the display convert the palette while it scans out removes the conversion from the blit and halves the amount of data written per frame.
