The CMake build sets XM7_VERSION 3 (linux-sdl/CMakeLists.txt:23,\nlinux-sdl/cmake/config_xm7.cmake:20), the FM77AV40EX/SX level, so every ROM\npath below is the XM7_VER >= 3 branch. RetroPie builds this repository with\nOpenGL and OpenCL off.\n\nROMs are read by file_load (linux-sdl/sdl/sdl_file.c:21-59), which prepends\nModuleDir and reads a fixed byte count. A file shorter than that count is\nrefused and anything past it is ignored. main sets ModuleDir to $HOME/.xm7/,\nor ./.xm7/ when HOME is unset (linux-sdl/sdl/windows_main.cpp:79-94). No hash\nor checksum of any ROM is computed.\n\nsystem_init stops at the first device whose init returns FALSE\n(linux-sdl/vm/system.c:124-127, 171, 203). MainLoop then sets error code 1\nand shows \"Error init VM. Please check ROMS and system-memory.\"\n(linux-sdl/ui-agar/agar_main.cpp:166-168, 546-548), and no machine runs. A\nROM whose absence makes its init return FALSE is required below.\n\nThe three drive sound effects are read with SDL_LoadWAV from RSSDIR, which\ndefaults to SHAREDIR, /usr/local/share/xm7/ (linux-sdl/sdl/build_config.h:76-86,\nlinux-sdl/sdl/api_snd2.cpp:660). The name is appended to that directory\nwithout a separator, and each name is tried in lower case, upper case,\ncapitalized and as written (linux-sdl/sdl/api_snd2.cpp:213-267). A missing\nWAV leaves its slot silent. HEADUP.WAV and HEADDOWN.WAV are compiled out\n(linux-sdl/sdl/api_snd2.cpp:160-163).\n\nUSERDIC.DAT is the FM77-211 learning RAM. It is filled with 0xFF when absent\nand written back by the emulator (linux-sdl/vm/jcard.c:77-82), so it is not\nlisted. JSUBMON.ROM, SUBSYS_8.ROM, SUBSYSL4.ROM, ANKCG16.ROM, the FM-8 and\nFM-7 boot ROMs and FBASIC10.ROM are only read when XM7_VER is 1.\n",
