VERSION 3.21, VKQUAKE2_VERSION\n\"1.5.10\", BASEDIRNAME = \"baseq2\" (qcommon/qcommon.h:26-30).\n\nFS_InitFilesystem reads the basedir cvar, default \".\", and mounts\n<basedir>/baseq2 (qcommon/files.c:858, 872). A non-empty game cvar adds\n<basedir>/<game> on top (qcommon/files.c:878-880, 640).\nFS_AddGameDirectory tries pak0.pak through pak9.pak in each directory and\nskips an index that does not open (qcommon/files.c:537-542).\n\nFS_LoadPackFile computes a checksum of the pak directory, but the\ncomparison against PAK0_CHECKSUM only runs with NO_ADDONS, which is\ncommented out (qcommon/files.c:24, 28, 484-489). No pak is rejected for\nits contents. The Vulkan renderer, vid_ref default \"vk\"\n(linux/vid_so.c:448), stops with ERR_FATAL when pics/colormap.pcx is\nmissing (ref_vk/vk_image.c:1640-1642). That file is in baseq2/pak0.pak.\n\nBatocera 43.1 copies /usr/bin/vkquake2 (binary, ref_*.so and the game\nlibraries of baseq2, ctf, rogue, smd, xatrix, zaero) into\n/userdata/roms/quake2, changes to that directory and runs ./quake2, with\n`+set game rogue|xatrix|zaero|smd` chosen from the ROM name (configgen\ngenerators/vkquake2/vkquake2Generator.py). The basedir is therefore\n/userdata/roms/quake2.\n\nMusic is read from <gamedir>/music/trackNN.ogg, .flac, .mp3 or .wav,\nthen from baseq2/music/ (client/snd_miniaudio.c:215-220, 241-246).\n",
