Editing the attribute table for more colorful sprites

Post by tgotr »

I am working on my first rom hack. Rom hacking Friday the 13th on the NES. I would like to edit the attribute table so the whole Jason sprite is more than three colors.

In my research, I've found NES Screen tool can do it, but I can not import the CHR dump that I got from famiROM. it says it's the wrong size. I've split the rom several times with different sizes, NESST won't take it.

What am I supposed to do? Is it because I already edited the rom before starting to use NES screen tool?

Forget "NES Screen Tool", it's not made for anything like this at all.

Jason is a bunch of sprites, so there is no involvement from the "Attribute Table", which is for background tiles only.

Sprites have attributes too, the second byte in sprite memory picks which of the 4 sprite palettes to use.

I can find that out using the PPU viewer and edit that with a hex editor, right?
