notes: |
|
|
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.

Scans pcsx2/bios/ for any file between 4 MB and 8 MB. Validates via romdir
|
|
structure parsing (RESET + ROMVER entries). User selects BIOS via core option
|
|
pcsx2_bios. Falls back to first valid BIOS found if configured BIOS is missing.
