GAMENAME = \"id1\"\n(Quake/quakedef.h:37).\n\nCOM_InitFilesystem takes the base directory from -basedir, otherwise\nhost_parms->basedir (Quake/common.c:2463-2467). COM_AddGameDirectory\nopens <basedir>/<dir>/pak0.pak, pak1.pak, ... and stops at the first\nindex that does not open (Quake/common.c:2241-2245). Right after\nid1/pak0.pak it mounts vkquake.pak, built from Misc/vq_pak and embedded\nin the binary (Quake/common.c:2257-2282). It carries default.cfg, three\nmenu pictures and entity fixes, no gfx.wad and no palette.\n\ngfx.wad and gfx/colormap.lmp come from id1/pak0.pak, and without either the\nengine stops with Sys_Error (Quake/wad.c:80-87, Quake/host.c:1093-1095).\ngfx/pop.lmp, present only in the registered id1/pak1.pak, sets the\nregistered cvar (Quake/common.c:1458-1484).\n\nCOM_LoadPackFile compares the file count (339) and the CRC of the pak\ndirectory against id1/pak0.pak v1.00, v1.01 and v1.06\n(Quake/common.c:56-59, 2105-2118). A mismatch only sets com_modified;\nthe file is still mounted. With com_modified set and no gfx/pop.lmp the\nengine stops (Quake/common.c:1464-1470), so -game, -hipnotic and -rogue,\nwhose paks differ from id1/pak0.pak, need the registered id1/pak1.pak.\n\n-rogue and -hipnotic add rogue/ and hipnotic/ after id1/\n(Quake/common.c:2507-2510). Batocera 43.1 runs\n`vkquake -basedir /userdata/roms/quake` and adds -hipnotic or -rogue\nfrom the ROM name (configgen generators/vkquake/vkquakeGenerator.py).\n\nBackground music is streamed from <game>/music/trackNN.<ext>, ogg, opus,\nflac, mp3 and wav, when present (Quake/bgmusic.c:29, 321).\n",
