|
|
Recalbox's standalone ARM port of Final Burn Alpha, lineage pifba (originally
|
|
by Franxis / Oopsware for the GP2X, modernised to SDL2 by Recalbox). The
|
|
binary is installed as fba2x and runs with a ZIP path on the command line
|
|
(rpi/main.cpp:187, "Usage: fba2x <path to rom><shortname>.zip").
|
|
|
|
BIOS and ROM archives are resolved relative to szAppRomPath, hardcoded to
|
|
"roms/" in rpi/bzip.cpp:4 and overridden only through the rom path argument.
|
|
BzipOpen (rpi/bzip.cpp:360-394) iterates BurnDrvGetZipName for every
|
|
BIOS/parent slot and opens "<roms/><name>" directly: no fallback
|
|
directory walking. Inside the opened archives each ROM is located by its
|
|
CRC32 first and by its names only when no member carries that CRC
|
|
(rpi/bzip.cpp:82-111), so member names are free.
|
|
|
|
Shared BIOS ROM sets flagged BDF_BOARDROM in the driver source:
|
|
- neogeo (burn/neogeo/d_neogeo.cpp), SNK Neo Geo system BIOS
|
|
- pgm (burn/pgm/d_pgm.cpp), IGS PGM board BIOS
|
|
|
|
CPS1 and CPS2 titles embed their program/encryption ROMs directly in each
|
|
game archive: no CPS board BIOS zip. CPS3 (burn/cps3/d_cps3.cpp) carries
|
|
the SH-2 BIOS as a BRF_BIOS member of each game's archive (red-earth,
|
|
jojo, sfiii, etc.), so there is no shared cps3.zip here either.
|
|
|
|
pifba is a FROZEN snapshot of Final Burn Alpha 0.2.97.x with ARM-specific
|
|
speedhacks (NEOGEO_HACKS, OOPSWARE_FIX, USE_SPEEDHACKS) and a reduced driver
|
|
set compared with upstream FBA / FBNeo: 32 BIOS entries in d_neogeo.cpp vs
|
|
~45 in modern FBNeo, no newer Neo Geo UniBios revisions (uni-bios.10 through
|
|
uni-bios.13 are commented out), no Hyper Street Fighter 2 refresh, and no
|
|
SNK Hyper NeoGeo 64. Keep this separate from fbalpha2012 (libretro port of
|
|
the same base) because it does not share binaries or load behaviour.
