Three changes to the search-list model, one commit because the readers
and the profiles must move together for the schema to hold.
Set requirement in a groups map. pom2 falls back on apple2.rom for the
][ and the ][+, and on apple2e.rom for the //e it boots and for the
unenhanced //e: one required on the file could not say both. A profile
now declares groups: {name: {required}}, a member writes no required
of its own (schema and validate_schemas refuse one) and load_emulator_
profiles derives it, true when one of its sets is. group takes a name,
a list, or a map from set to rank where the rank differs per set. pom2
is grouped from SystemProfile.cpp and MainWindow.cpp:246-296 at its pin.
One member per required set under --required-only. The pick is the
first the code reads among the held members the region filter leaves,
by rank then declaration order; a set the platform declares a member
of is carried by that declaration. The emulator pack, verify
--emulator, the platform pack, its manifest and verify --platform read
alternatives.required_only_spares or core_file_spares.
variant_group is now selection_slot: files a core chooses between by
a rule other than first found (disc territory for PicoDrive and
Pizza Boy SC, the o2em_bios option, a WebAssembly probe in SWF
Player). Where the code takes any one, the field became a group:
ARMSX1 (ArmSxBackend.java:149-157, name order), ePSXe (load_bios
0x433540-0x433621 of the 2.0.5 Linux x64 binary, one configured path,
HLE when BiosHLE is set), FPse and FPse-NG, DXX-Rebirth's HOGs
(inferno.cpp:472-512). odin and zesarux carried it with no effect.
slot.py compares ranks only between candidates that share a set.
Each list read at the profile's pin, every member required: true where
the code needs one of the set, the order left in priority.
- yabause, yabasanshiro, kronos: libretro.c tries saturn_bios.bin,
sega_101.bin, mpr-17933.bin (yabause 1035-1049, yabasanshiro
1048-1071, kronos 1619-1638 after kronos/saturn_bios.bin). kronos
also reads saturn_bios.bin at the system root, now its own entry.
yabasanshiro refuses the game with no file even under forced HLE
(1064-1071), so its hle_fallback is gone.
- yabadabadoo: bios_for_region (libretro.c:262-284) takes any of the
three in an order the disc region picks. One group, no priority:
region keeps that order, no single rank would be true.
- ymir libretro: kBiosFilenames (libretro.cpp:305-309), region first,
else the first found, no game without one (1231-1236).
- duckstation: FindBIOSImageInDirectory (bios.cpp:397-450) keeps any
image of the right size, a region mismatch only warns: one set.
- picodrive: find_bios walks one list per disc region
(libretro.c:1272-1336), three groups.
- px68k: BIOSFILE then cgrom.dat or cgrom.tmp (libretro.c:984-1032).
- px68k-sdl: BIOSFILE and FONTFILE lists (winx68k.cpp:277-331).
- numero: ti83se, ti83plus, ti83 (libretronew.cpp:575-594), no ROM
leaves a blank screen.
- freechaf: sl90025 then sl31253, HLE without either
(libretro.c:186-199), optional set.
- pcsx1: scph1001, scph5501, scph7001 then any scph* (libretro.c:1229),
HLE without, optional set.
- odin: three boot ROMs inside hikaru.zip.
Font caches synthesised from host fonts, battery images and backup RAM the emulator creates when absent, user symbol maps, the BAM presets list and the BOOT -bios image slot have no canonical copy.
Each standalone profile records where its version is read: the source
at its pin (clk 2026-07-23-136-g9020107, shadps4 0.20.1 WIP, eden
v0.2.0-401-g26a03d2), the APK, binary or archive read (kind package),
or, where no reading can be made, kind unverified with the reason: a
host the tools cannot read, a forge gone or not answering, no build
recorded as read, a pin on another branch. Those keep their value,
unconfirmed.
RetroPie builds the master tip (RetroPie scriptmodules/emulators/px68k.sh:15 at 46128cd2). The one commit since e29ce400 bounds string copies in SDL/winui.c; no file is read differently.
RetroPie builds minivmac/minivmac, winterheart/quasi88 and TurtleBazooka/px68k under the package names minivmac, quasi88 and px68k (scriptmodules/emulators/minivmac.sh:12, quasi88.sh:12, px68k.sh:12). With built_by retropie and those names in cores, RetroPie resolves them to minivmac37, quasi88kai and px68k-sdl, while its libretro builds stay reached through retroarch. Measured: RetroPie keeps 532 of 532 platform files OK and gains the 14 files the standalone builds read; no other platform's resolution changes.
IPL search order iplrom, iplromxv, iplromco, iplrom30 and font cgrom30, cgrom30.tmp, cgrom, cgrom.tmp (SDL/SDL2/winx68k.cpp:277-331), SCSI ROMs (:140-271), all from $HOME/.keropi (SDL/prop.c:172-194). One IPL and one font are required: without them the CPU loop never starts.
