Each PCSX2 fork declares how its LoadBiosVersion reads the table: the strncmp length on RESET, the NUL test on names, EXTINFO, and what a read past the end does, from the source at the pin or the shipped libemucore.so for NetherSX2 and its Turnip builds. The Recalbox libretro PCSX2 and PCEE2 check no size, so their 4 to 8 MB bounds are gone, and the PCEE2 and ARMSX2 arcade images require the COH-H zone.

Filename-agnostic BIOS detection. Scans bios/ for any file between 4-8 MB
|
|
with valid romdir structure (RESET + ROMVER entries). No hash validation.
|
|
Companion files (.rom1, .rom2, .nvm, .mec) derive their names from the selected BIOS.
|
|
ROM1 (DVD player) and ROM2 (Chinese extension) silently skipped if missing.
|
|
NVM and MEC auto-created with defaults if missing.

ROMVER 0220JD20121227, the PS2 BIOS the PS3's ps2_emu carries. Cut from
|
|
dev_flash/ps2emu/ps2_emu.self of PS3 system software 4.90, decrypted by
|
|
RPCS3, from 0x12F bytes before "compatible mode" to 0x262 bytes after
|
|
"Parity error" and padded to 4 MiB, as firmware_bios_claim release 2
|
|
does. Accepted like any image with a valid romdir.
