Hi guys. Plz post here all related info. Here is my simple PS2 BIOS unpacker - http://brokensword.narod.ru/ps2bios_unpacker.zip. It just unpacks bios image to .elf files. For exemple, my Europe v.2.00 (14/06/2004) (btw, how pcsx2 knows it?) bios contains 59 .elfs.

just launch ps2bios_unpacker.exe dump.bin
post here results of your reverseing progress.

The download is definetly corrupt. I'm using Winrar, Winzip, and Windows XP and they all say corrupt. I've redownloaded 10+ times using both Mozilla Firefox and Internet Explorer (evil).

Sorry guys for damaged zip. PS2 BIOS unpacker has been updated, new version extracts file-modules from BIOS image useing ROMDIR structure, produces self-explanatory filenames and includes source code. Plz, check it now. The link is the same:

Here is reversed modules info (in alfabetical order):


Module name Type Description

ADDDRV ELF file ???????????
CDVDFSV ELF file CDVD driver
CDVDMAN ELF file CDVD driver part?
CLEARSPU ELF file ???????????
DMACMAN ELF file DMA driver part?
EECONF ELF file EE config
EELOAD DATA EE data
EELOADCNF DATA EE loader config
EENULL DATA ???????????
EESYNC ELF file ???????????
EXCEPMAN ELF file Exception manager
EXTINFO DATA Extended BIOS info
FILEIO ELF file FILEIO service
FNTIMAGE DATA Font image data
FONTM DATA ???????????
HEAPLIB ELF file Heap library
ICOIMAGE DATA Icon images
IGREETING ELF file ???????????

to be continued...

plz, post here your info.

P.S. to pcsx2 developers: guys, i think you've reversed each BIOS byte for creating your great emulator. How did you do that ?). It requires very high reversing skills, or maybe you just paid Sony something ?) If so - how much? ;)
