Technical notes

Frozen snapshot of MAME 0.37b5 via iMAME4All (David Valdeita). Fastest and least accurate MAME core. Supports ~2000 arcade games from the 0.37b5 ROM set.

BIOS handling follows MAME 0.37b5 conventions. Shared BIOS files are packaged as parent ROM ZIPs (e.g. neogeo.zip) and placed in the ROM directory alongside game ROMs. The core searches only the ROM directory for ROMs and BIOS sets.

Samples (per-game WAV files) are loaded from system_dir/mame2000/samples/. They provide sound effects for certain games and are optional.

hiscore.dat, history.dat and mameinfo.dat are loaded from the ROM directory. cheat.dat is loaded from system_dir/mame2000/cheat/. hiscore.dat and cheat.dat are bundled in the core repo (metadata/).
