ArkOS ran the GBA with gpsp_ezode_mod and dArkOS with mgba_rumble: no profile named them, so an install for the card's games kept every GBA core's files, FBNeo's 3,472 data files among them. Each rename proven from the OS build (same code base, same BIOS loading) joins its profile's cores. The resolver folds either separator, and falls back to the emulator column when the core names a mode, a machine or a plugin of that program, only where its profile declares the folder's system: MAME documents no GameKing ROM. 109 unresolved names are 56, each one recorded with why in tests/test_games_index.py.

notes: >

|
HLE BIOS built-in: core option pcsx_rearmed_bios = "HLE" bypasses real BIOS entirely.
|
|
Default is "auto" which searches system dir for listed filenames, then scans all files.
|
|
Region detection reads bytes at offset 0x7ff51: " E" = EU, " J" = JP, else US.
|
|
Three CRC32 hardcoded as JP override: 0x18D0F7D8, 0x3B601FC8, 0x3539DEF6 (psxonpsp, scph1000).
|
|
BIOS validity check: byte pattern at offset 1 (\x00\x08\x3c\x3f) or string "PS compatible" at 0x12c
|
|
(frontend/libretro.c:3632, 3646-3651): a file failing it is skipped, hence validation [size, signature].
|
|
Files named "unirom" (case-insensitive) are explicitly skipped.
|
|
Region fallback: if the matching-region BIOS is missing, any available region BIOS is used over HLE.
|
|
Three region slots: US (index 0), JP (index 1), EU (index 2) stored in Config.Bios[].
