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.

notes: |
|
|
pcsx2/resources/GameIndex.yaml, the per-game patch, settings override and
|
|
compatibility database, is the one the buildbot publishes in LRPS2.zip (the
|
|
lrps2 data directory). An OSD warning is shown if it is missing, and some games
|
|
do not boot without it.
|
|
Hard fork of PCSX2 (pre-Qt, 1.7-dev era) ported to libretro. x86_64 only.
|
|
BIOS detection is filename-agnostic: scans pcsx2/bios/ for any file between 4-8 MB
|
|
with a valid romdir structure (RESET + ROMVER entries). No hash validation.
|
|
Companion files (.rom1, .rom2, .nvm, .mec) derive paths from the selected BIOS.
|
|
DEV9 (network/HDD) and USB are stubbed in the libretro port.
|
|
Widescreen patches are largely compiled into the core (libretro/patches.cpp).
|
|
.info firmware_count=2 counts the bios folder and GameIndex.yaml.
|
|
.info description mentions EROM.BIN but no EROM loading path exists in the code.
