Dragon Ball Z Super Butouden

[Deathbringer]

I took a look at it and can confirm 3 things:
1. ^What he said.

2. The battle sprites are not TIM format, so even using a savestate with PSicture isn't going to work.

3. The sprites are 8bpp, but the palette looks to use up to 64 colors (or at least Super Goku and The Great Saiyaman do).

And that was through the emulator, I could take a look through the files now knowing for sure that they are 8bpp.
