Frozen snapshot of Final Burn Alpha v0.2.97.29 (circa 2012), full version. NOT an alias of FBNeo — different codebase, different ROM set compatibility. Supports CPS-1, CPS-2, CPS-3, Neo Geo, PGM, Sega, Cave, Toaplan, and more. Exists for RAM-constrained platforms. Most users should use FBNeo.

Multiple arcade systems have BIOS ROMs marked BRF_BIOS in source:

Neo Geo (d_neogeo.cpp:923-1011): neogeo.zip ROM set contains ~35 BIOS variants - 68K BIOS: asia-s3.rom (default), sp-s2.sp1, sp-s.sp1, sp-u2.sp1, sp-e.sp1, vs-bios.rom, sp-j2.sp1, sp1.jipan.1024, sp-45.sp1, japan-j3.bin, neo-po.bin, neo-epo.bin, neodebug.bin, sp-1v1_3db8c.bin, 16 Universe BIOS variants, neopen.sp1, plus PCB/CD/trackball BIOS variants - Z80 BIOS: sm1.sm1 (sound program) - Graphics: sfix.sfix (text layer tiles) - Data: 000-lo.lo (zoom table) - Neo Geo CD: neocd.bin

PGM (d_pgm.cpp:303-379): per-game BIOS sets in each ROM ZIP - pgm_t01s.rom (text tiles), pgm_m01s.rom (samples), pgm_p01s.u20/pgm_p02s.u20 (68K BIOS v1/v2), ddp3_bios.u37, bios.u42, svg_bios.u49 (custom per-game)

CPS-3 (d_cps3.cpp): 18 SH-2 BIOS variants, 512 KB each, region-specific (see fbalpha2012_cps3.yml for full list)

Sega System 16B (d_sys16b.cpp:8900): ism2006v00.u1

All BIOS files are part of their respective game ROM set ZIPs (arcade standard). None are standalone system directory files. The .info note "BIOS files must be inside the ROM directory" refers to the ROM directory containing the game ZIPs, which already include their BIOS — no separate action needed by the user.

ROM path: g_rom_dir from content path. g_system_dir set but unused. Extensions: iso|zip|7z. need_fullpath=true, block_extract=true.
