Sakura Taisen: Mysterious Paris AGO files (PS2)

Post by SMP112 »

It's been a while but I've come back to ask for some help once again

As the title says I'm trying access this particular file type for the game. Looking in a hex editor it starts off with AGO magic header with BMP directly below it

The raw image starts at offset 0x800, 32bit (specified at offset 0x2c), 640x288 (specified twice at offset 0x34 and 0x3c as 16bit), RGBA interleaved.

Hm I see. Guess I'll use a texture finder then. Thanks

If most of the files have the same size you can also try something else like renaming all their extensions as .RAW and opening them with IrfanView, it will open a dialog asking for the information I provided in the previous post:
Image width: 640
Image height: 288
File header size: 2048
BPP: 32
Color order RGBA
Interleaved

The settings remain saved so you can open all of the files with these correct settings.
Just an idea :)
