Abdessamad Derraz 5004c4d8d5 fix: refuse an archive holding no declared member 
_holding_members kept every same-named copy when the best held nothing,
so galgames.zip, a lone assembler listing, resolved by name for mame,
groovymame and mame4droid-2024, and awbios.zip for mame4droid. Such a
copy now resolves as hash_mismatch.

mame2003_plus declared its contents by name only, while fileio.c:1031-1040
loads a member by CRC when the name is absent. The 61 members now carry
the CRC their driver declares, so stvbios, megatech and the six ZN sets
keep matching the archives the collection holds.

notes: |
MAME 2003-Plus is a libretro port of MAME 0.78 with backported drivers, bug fixes,
and new game support contributed after the original 0.78 snapshot. It targets
low-end hardware (Raspberry Pi, handhelds) while expanding game compatibility
beyond stock 0.78.
BIOS handling follows standard MAME conventions. Each arcade board with a shared
BIOS defines a parent ROM set. Game drivers reference this parent, and the emulator
merges the parent ZIP contents at load time.
BIOS ZIPs must be in {content_dir}/ (same folder as the game ROMs).
The core resolves parent ROMs by walking the clone_of chain within the
content directory only (osd_get_path returns content_path for FILETYPE_ROM).
ROM naming follows MAME 0.78 conventions with some updates from the Plus patches.
Requires a mame2003-plus-specific romset for full CRC32/SHA1 compatibility.
Neo Geo uses mame.sm1, mamelo.lo, sfix.sfx naming. PGM uses pgm_p01s.rom naming.
ZN-1/ZN-2 boards are present but most games are NOT_WORKING (incomplete PS1
emulation in the 0.78 codebase). PGM and ST-V have partial support.
Data files go in {system_dir}/mame2003-plus/. Samples in samples/ subfolder,
artwork in artwork/ subfolder (both per-game ZIPs). hiscore.dat is compiled
into the binary and auto-generated on first run if absent.
