Each PCSX2 fork declares how its LoadBiosVersion reads the table:
the strncmp length on RESET, the NUL test on names, EXTINFO, and what a
read past the end does, from the source at the pin or the shipped
libemucore.so for NetherSX2 and its Turnip builds. The Recalbox libretro
PCSX2 and PCEE2 check no size, so their 4 to 8 MB bounds are gone, and
the PCEE2 and ARMSX2 arcade images require the COH-H zone.
RetroBat and Batocera list ps3_ps2_emu_bios.bin, the PS2 BIOS the PS3
carries for ps2_emu. RPCS3 installed the held PS3UPDAT.PUP (4.90,
sha1 093f8698) and decrypted dev_flash/ps2emu/ps2_emu.self, and the
image is the span firmware_bios_claim release 2 cuts, padded to 4 MiB.
Its romdir parses and ROMVER reads 0220JD20121227. Two runs give the
same bytes, sha1 2dc921be.
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.
DEV9 opens eeprom.dat and flash.dat by bare name (pcsx2/DEV9/DEV9.cpp:144
at f0523f8a, AetherSX2 DEV9/flash.cpp:89, PCSX2 1.6 dev9ghzdrk/flash.cpp:73),
so the process working directory answers, never the BIOS folder. Only
yaps2 said so: the other PCSX2 profiles had the file packed into the BIOS
folder and the RetroDECK export add it there.
PCSX2 and its forks keep the first 4 to 8 MB image with a romdir in
the BIOS folder (pcsx2/ps2/BiosTools.cpp:258-282, 317-332 at f0523f8a),
and PCSX2 1.6 lists the same test in its BIOS picker
(BiosSelectorPanel.cpp:151-177). The names are labels. Without found_by
the truth model read ps2-0230a-20080220.bin as a name the core opens, and
the RetroDECK export added it as a required file.
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.
One run of profile_sync --all --rebase-refs --fresh. Every guard held:
no ref to review, no prose left under an older pin, no file name or hash
literal gained in a cited file since the pin, no built_by pin and no pin
keyed by build mode. The site's record of cited source paths is rebuilt
with them.
Same chain as the first pass: no ref to review, no file name or hash
literal added to a cited file since the pin, no profile a single
platform builds at a fixed commit, refs recaled with their pins, and the
written prose read again.
Every cited block was read again at HEAD: no ref left to review, no
file name or hash literal added to a cited file since the pin
(--detect-new-files --watch-hashes), refs recaled with their pins.
Profiles built by a platform at a fixed commit, or whose bump would
leave prose under an older pin, stay where they were.
ps2-0250j-20100415.bin passes the folder scan of pcsx2, armsx2 and yaps2. EmuDeck's SCPH-70004 .BIN, .ROM1 and .ROM2 are aliases in pcsx2, and the .rom1 note now says the stat is case-sensitive.
Upstream moved under 145 profiles: 679 refs shifted and 452 followed a
renamed file, against 6,483 that still anchor where they were written.
The recale rewrites the located ranges only, keeping the annotations and
the sentences that carry them, and 106 pins advance in the same commit
because refs and source_commit name one revision or the profile
describes two at once.
Nothing here was guessed. The 183 refs that are CHANGED, GONE or
AMBIGUOUS are untouched, and the 57 profiles holding them keep their old
pin until someone reads the diff: profile_sync refuses to recale a
profile while any of its refs needs a re-read. trident kept its pin too,
its annotated ref being one the writer will not rewrite.
bios_mode: agnostic (profile) and agnostic: true (file) for
emulators that accept any valid BIOS without specific filename.
find_undeclared_files skips agnostic entries, pack extras scan
includes all matching DB files by path prefix + size criteria,
resolve_local_file has agnostic fallback with rename README.
applied to pcsx2, lrps2 (bios_mode), melonds dsi_nand (file).
aliases must be same-SHA1 alternative names, not distinct files.
pcsx2: 164 different BIOS dumps are separate DB entries, not aliases.
melonds: 6 regional NAND dumps are separate DB entries, not aliases.
also cleans pcsx2 non-standard fields, fixes display_name.
Every profile now has:
- profiled_date: date of source code analysis
- core_version: version from libretro-core-info .info files
- display_name: human-readable name from .info files
260/260 profiles complete. 294/294 libretro cores covered.
Standalone emulators (cemu, rpcs3, xemu, vita3k) versioned manually.
- Added profiled_date field to all 204 existing profiles for update tracking
- Created 56 alias profiles for cores that share BIOS with a parent
(e.g., mednafen_psx -> beetle_psx, fbalpha2012 -> fbneo)
260 total profiles covering all 294 libretro cores (204 unique + 56 alias).
