notes: |
|
|
Frozen snapshot of Final Burn Alpha v0.2.97.28 (circa 2012), CPS-2 only.
|
|
NOT an alias of FBNeo — different codebase, different ROM set compatibility.
|
|
Exists for RAM-constrained platforms (3DS, embedded). Most users should use FBNeo.
|
|
|
|
CPS-2 has no system BIOS. Each game's ROM set is self-contained:
|
|
68000 program ROMs + Z80 sound program + GFX ROMs + QSound samples.
|
|
|
|
QSound is emulated in software (qs_c.c:QscInit, panning table + DSP emulation).
|
|
No external QSound DSP ROM (dl-1425.bin) needed — unlike MAME, FBA emulates
|
|
the QSound chip directly without requiring the DSP program ROM.
|
|
|
|
Z80 sound program loaded from game ROM set into CpsZRom buffer (cps.c:451,
|
|
BurnLoadRom). QSound samples loaded into CpsQSam. All from the game ZIP.
|
|
|
|
Board PLDs (buf1, ioa1, prg2, rom1) referenced via A_BOARD_QSOUND_PLDS
|
|
macro, all marked BRF_OPT. GAL/PAL dumps for hardware preservation only.
|
|
Zero BRF_BIOS entries in entire codebase.
|
|
|
|
ROM path: ROMs loaded from content directory (g_rom_dir, libretro.cpp).
|
|
g_system_dir is set (line 988) but never used for any file loading.
|
|
|
|
The .info note "BIOS files must be inside the ROM directory" is misleading —
|
|
there are no BIOS files for CPS-2. Generic note across all FBA cores.
|
|
|
|
need_fullpath=true, block_extract=true, extensions=zip.
