Technical notes

Frozen snapshot of Final Burn Alpha v0.2.97.28 (circa 2012), CPS-1 only. Exists for RAM-constrained platforms (3DS, embedded). Most users should use FBNeo.

CPS-1 has no system BIOS. Each game's ROM set is self-contained: 68000 program ROMs + Z80 sound program + GFX ROMs + (optional) QSound samples. QSound games (Cadillacs & Dinosaurs, etc.) include audio samples directly in their ROM set (cd-q1.1k through cd-q4.4k), not as a separate DSP BIOS.

Board PLDs (buf1, ioa1, prg1, rom1, sou1) are listed in ROM definitions as BRF_OPT (optional). These are GAL/PAL dumps for hardware preservation — never loaded by the emulator.

ROM path: ROMs are loaded from the content directory (g_rom_dir). system_directory (libretro.cpp:2202) is used only for hiscore.dat.

The .info note "BIOS files must be inside the ROM directory" is misleading — there are no BIOS files for CPS-1. This note is generic across all FBA cores.

244 ROM sets defined (488 STD_ROM_PICK/FN entries = 244 games). is_experimental=false, need_fullpath=true, block_extract=true.
