Hey guys I'm just wondering if anyone has any info on where in the PS2 Bios the intro sounds/graphics are stored like those cubes.
I unpacked the BIOS of my PS2 which was a collection of ELF functions
7F 45 4C 46 signature just split the files up and looking through the strings I see like
rom0
S2LOGO
imagedata/osd_logo_B.raw
etc anyone have a clue? I thought it would be cool to get these assets out and remake the intro in unreal or something.
-edit-
Found some more interesting stuff inside of the BIOS one of the elfs
Seems to be the function that loads the audio.
