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.
