NUM_ID_PAKS 9, NUM_TA_PAKS 4 (code/qcommon/qcommon.h:597-598).\n\nfs_basepath defaults to Sys_DefaultInstallPath, the directory of the\nbinary (code/qcommon/files.c:3323, code/sys/sys_main.c:88-94, 738).\nFS_Startup mounts baseq3 under fs_basepath and fs_homepath, then fs_game\nwhen set (code/qcommon/files.c:3362-3377, 3396-3409). FS_AddGameDirectory\nmounts every .pk3 of each directory (code/qcommon/files.c:2933).\n\nFS_CheckPak0 compares the pak checksum of baseq3/pak0.pk3 through\npak8.pk3 and missionpack/pak0.pk3 through pak3.pk3 to pak_checksums[] and\nmissionpak_checksums[] (code/qcommon/files.c:179-197, 3486, 3516). The\nvalue is a block checksum over the CRC32 of every member\n(code/qcommon/files.c:2111), not a file hash. A mismatch prints a warning and the pak stays\nmounted. A missing baseq3 pak is fatal unless the engine runs standalone,\nwhich needs com_basegame other than baseq3 (code/qcommon/files.c:3570-3572,\n3596-3619). Once any Team Arena pak is found the four are required\n(code/qcommon/files.c:3622-3640). demoq3/pak0.pk3 with\nDEMO_PAK0_CHECKSUM counts as baseq3/pak0.pk3 (code/qcommon/files.c:178,\n3475-3479, 3580-3590).\n\nBatocera 43.1 installs the binary as /usr/bin/ioquake3/ioquake3 and runs\nit through the ioquake3 generator, which copies /usr/bin/ioquake3 into\n/userdata/roms/quake3 and starts /userdata/roms/quake3/ioquake3 with the\narguments written in the ROM file (configgen\ngenerators/ioquake3/ioquake3Generator.py). fs_basepath is therefore\n/userdata/roms/quake3.
