RetroBat and Batocera list ps3_ps2_emu_bios.bin, the PS2 BIOS the PS3 carries for ps2_emu. RPCS3 installed the held PS3UPDAT.PUP (4.90, sha1 093f8698) and decrypted dev_flash/ps2emu/ps2_emu.self, and the image is the span firmware_bios_claim release 2 cuts, padded to 4 MiB. Its romdir parses and ROMVER reads 0220JD20121227. Two runs give the same bytes, sha1 2dc921be.

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.
