mame2000 opens hiscore.dat, history.dat and mameinfo.dat from IMAMEBASEPATH, the content directory (src/libretro/fileio.c:1002-1014, libretro.c:1044-1052). mame2014 and mame2015 open hiscore.dat through emu_file with no search path, the working directory (src/emu/hiscore.c:330-337, fileio.c:141-143). With no load_from the entries claimed system/ and the packs shipped files neither core opens there. ANoteOutsideTheSystemDirCarriesLoadFrom holds libretro notes and load_from together.

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/).
