HBMAME (Homebrew MAME) - RetroBIOS¶
Technical notes
Fork of MAME 0.220 preserving homebrew and hacked arcade games. Builds as TARGET=hbmame with 191 driver files covering 8511 game entries. Drivers are hack/homebrew variants of CPS1, CPS2, CPS3, Neo Geo, Pac-Man, Galaxian, etc.
BIOS handling is identical to MAME. Neo Geo drivers reuse the standard neogeo.zip BIOS set via unmodified NEO_BIOS macros (neogeo.h). No other HBMAME driver defines ROM_SYSTEM_BIOS entries. BIOS files are expected as MAME-format ZIP archives in the ROM search path.
Data directories (artwork, cheat, hash, ini, samples) can be placed in {system_dir}/mame/ but are optional and game-specific.
No BIOS or firmware files required.
Why no files
BIOS ROMs are inside parent ROM set ZIPs (neogeo.zip, etc.) following MAME convention. No standalone system directory files.
