lrps2 names no hash for its GameIndex.yaml, and the only full-tail copy was ARMSX2's: it counted as path proof and replaced the file RetroArch pins on desktop targets, which have no ARMSX2. Upstream PCSX2 took ARMSX2's patches.zip by name the same way. A copy in another emulator's tree now proves nothing at any tail length, and LRPS2's own GameIndex comes from the tree the buildbot publishes.

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; 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.
