Hello there!

Can somebody please help update my noesis script to support this format? 

SCE_GS_PSMT8 = 19, // 8-bit indexed, packing 4 pixels per 32-bit.

So far I came across 4 formats and this one is something... Don't know how to process it in noesis.

Here is 010 Template from Nenkai

And here is my noesis script... Thanks in advance!

If you change your line in the script to:

data = rapi.imageDecodeRawPal(data, Palette, TexWidth, TexHeight, 8, "r8 g8 b8 a8", noesis.DECODEFLAG_PS2SHIFT)

Seems to look correct with that flag enabled.

Well seems like i can't get over these. It looks like they are stored as blocks.

I noticed that file 0x0005da40.img is constructed from 2 images leads to single one.

Also can't believe it that file 0x0002cb40.img store over 70+ textures. But maybe yes since they are all low res.

Use template to show more info.

If anyone know a way please post a solution. Noesis script would be perfect but anything else also. Thanks in advance!
