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.

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.
