Game's using this packing format (preferably this one) are a mess to datamine (heck even modify) unfortunately, ESPECIALLY IF YOU STRIP THE SYMBOLS due to every SINGLE file name and offset is hardcoded. I tried for a long time to find the textures that were compressed, they were definitely raw images of some sort but I never got the proper image and/or its color format, I don't even understand the header... Can someone crack these, so this game can be dissected more aside from debugging material and unused strings? A Noesis script I would like if possible, or at least give info about the format if you do.

both images look like etc1 with split alpha
in your 00000000.dat sample the color data starts at 0x25b0
the alpha data starts at 0x8254b both 1024x1024
in your 00000001.dat sample the color data starts at 0x4b
and the alpha data starts at 0x2004f both 512x512
the size of the data is stored before the data.
if you're in a hurry you can use PVRTexTool, thats all i got for now.

There may be more, I'll mention more compression formats if I find them, thanks anyway

Do you have images of the raw images in their proper pixel formats and sizes? I cannot really understand your text...

Afaik, this isn't the same as BSPRITE.

Update: I'm an idiot, this is BSPRITE.

Turns out UNO & Friends also uses this format. Guess they were made by Aurora Game Tools. Blame GL for skipping 2 internally.
