Each EDK2 code image was run through a .qemu_cmd_line with -bios in the buildbot qemu_libretro.so (linux x86_64, 2026-07-27, 06ad814b) under scripts/core_probe.py, every pc-bios file staged in system/qemu.
edk2-aarch64-code.fd and edk2-arm-code.fd reach the TianoCore boot screen on -M virt with ramfb. edk2-x86_64-code.fd makes QEMU exit at once, as bios-256k.bin on the same command line does not: the x86 images are 3653632 bytes, not a multiple of 64 KiB, and x86_bios_rom_init refuses them (hw/i386/x86-common.c:1000-1002), the i386 and secure images included. edk2-riscv-code.fd leaves a black screen: it is S-mode code for pflash0 (docs/system/riscv/virt.rst:59-70).
The x86 and RISC-V images are read only as pflash drives, opened by path from the content folder, so the five entries are removed.
The core is built by libretro-gitlab-build.sh (Makefile.libretro-gitlab, the MAKEFILE of .gitlab-ci.yml) with a --target-list of 17 softmmu targets, and neither hppa-softmmu nor microblaze-softmmu is among them. hw/hppa/machine.c and hw/microblaze/ are not compiled, so nothing reads hppa-firmware.img, hppa-firmware64.img or the two Petalogix device trees. The four entries and the hppa system are removed.
Entries that cited only pc-bios/meson.build now cite the code that opens them.
bios-256k.bin is the firmware of the pc and q35 machines (pc_piix.c:466, pc_q35.c:349) and pc is the machine the core starts for an .iso, so it is required, and a missing image exits in x86_bios_rom_init. bios.bin is read only by the ISA PC or when the firmware option is cleared, so it is optional. qboot.rom is microvm's firmware with ACPI off. The pxe-*.rom images and efi-eepro100.rom are read through a romfile= option, the EDK2 code images through -bios.
The three EDK2 variable store templates and vof-nvram.bin are removed: no code resolves them through the data directory, a pflash drive is opened by path and the core runs from the content folder (ui/libretro.c:697).
Each libretro profile records version_basis and core_version is read
there at its pin. snes9x states 1.63 in snes9x.h, nestopia 2.0.0, mgba
0.11.0, vice 3.10, atari800's libretro tree 7.0.0. Cores whose build
takes its version from git carry the nearest tag in describe form
(flycast v2.7-90-ge88b0ce, ppsspp, duckstation, gearcoleco), placeholders
copied from .info files (Git, SVN) are replaced by the code's statement,
and a code that states none is null with kind none.
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.
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.
Profiles that read two repositories, a libretro port and its upstream,
now prefix each citation with source or upstream, decided by which tree
carries the cited value at its pin. The emulator pages use the word to
tell libretro glue, emulator code as the port carries it, and the
upstream emulator apart.
Each platform's own packages were read at the revision our data pins, for every emulator and core it ships: Batocera, Recalbox, RetroPie, ROCKNIX, Lakka, RetroDECK, RetroBat and EmuDeck. Files a package installs where the emulator reads them are recorded with installed_on, and files a release bundles but a package leaves out with not_bundled_on, so each platform's pack brings what its users lack and nothing they already have. The standalone profiles never checked before were held against their releases the same way. Batocera's imame4all is the mame2000 core. The primary neogeo.zip was a 7.7 KB placeholder no platform pins and no pack served: removed, the real dumps stay in .variants.
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.
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).
