Entries without a system in multi-system profiles were left unattributed by the truth model, and four System.dat additions left the export. Each system is read from the core's code at its pin. hiscore.dat, cheats and history serve every running machine (mame2000 cpuintrf.c:664-666, mame2003 cpuexec.c:280-282, mame2003_plus cpuexec.c:296-298, fbneo hiscore.cpp:154-161 gated on BDF_HISCORE_SUPPORTED), all arcade in those builds, so arcade. BIOS sets take the id their driver gives in the other MAME profiles, and bctvidbs is barcrest-mpu4 everywhere. Files serving several systems of one build (groovymame data files, raine) keep no system. Core resolution is unchanged on every platform.

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/).
