Technical notes

Frozen snapshot of Final Burn Alpha v0.2.97.29 (circa 2012), CPS-3 only. Exists for RAM-constrained platforms. Most users should use FBNeo.

CPS-3 uses a Hitachi SH-2 CPU with per-game, per-region BIOS ROMs. Each BIOS is a 512 KB (0x080000) 29F400 flash chip dump, region-locked. BIOS ROMs are marked BRF_ESS | BRF_BIOS in the ROM definitions.

BIOS is loaded into RomBios (cps3run.cpp:1048-1064), byte-swapped to little-endian, then decrypted via cps3_decrypt_bios() (cps3run.cpp:255). The SH-2 boots from BIOS, which initializes hardware and loads the game program from simulated flash/CD-ROM.

BIOS files are INSIDE the game ROM set ZIP (arcade standard), not separate system directory files. Each game variant has its own region BIOS.

Unique BIOS ROMs across all ROM sets (CRC32 from source): sfiii_usa.29f400.u2 0xfb172a8e SF3: New Generation (USA) sfiii_japan.29f400.u2 0x74205250 SF3: New Generation (Japan) sfiii_hispanic.29f400.u2 0xd2b3cd48 SF3: New Generation (Hispanic) sfiii_asia_nocd.29f400.u2 0x73e32463 SF3: New Generation (Asia NoCD) sfiii2_usa.29f400.u2 0x75dd72e0 SF3: 2nd Impact (USA) sfiii2_japan.29f400.u2 0xfaea0a3e SF3: 2nd Impact (Japan) sfiii2_asia_nocd.29f400.u2 0xfd297c0d SF3: 2nd Impact (Asia NoCD) sfiii3_euro.29f400.u2 0x30bbf293 SF3: 3rd Strike (Euro) sfiii3_usa.29f400.u2 0xecc545c1 SF3: 3rd Strike (USA) sfiii3_japan_nocd.29f400.u2 0x1edc6366 SF3: 3rd Strike (Japan NoCD) jojo_usa.29f400.u2 0x8d40f7be JoJo's Venture (USA) jojo_japan.29f400.u2 0x02778f60 JoJo's Venture (Japan) jojo_asia_nocd.29f400.u2 0x05b4f953 JoJo's Venture (Asia NoCD) jojoba_japan.29f400.u2 0x3085478c JoJo's Bizarre Adventure (Japan) jojoba_japan_nocd.29f400.u2 0x4dab19f5 JoJo's Bizarre Adventure (Japan NoCD) jojoba_euro_nocd.29f400.u2 0x1ee2d679 JoJo's Bizarre Adventure (Euro NoCD) redearth_euro.29f400.u2 0x02e0f336 Red Earth (Euro) warzard_japan.29f400.u2 0xf8e2f0c6 Warzard (Japan)
