saveIndexed = true in [options] saves the CLUT4/CLUT8 textures listed in [indexed] as palette PNGs, saveIndexed = all saves every one of them. The file is named <hash>_indexed.png, with the CLUT hash zeroed so one file serves every palette of the texture. The other textures are dumped as before. The indices are decoded from PSP memory and the palette comes from the current CLUT, so the dump looks like the game's texture. Add the file to [hashes] and [indexed] to use it as a replacement.
