PS2 BIOS reverseing

[Robert]

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.
