Do you know where the actual palette colors are stored? Not the values that decide which palettes to use. They're hiding in some kind of Little Indian-type code that I can't find. I'm about to start paletting everyone, but I count 2 to 5 sub-palettes from sub-palettes 1 and 2 that I would like to replace before I decide which palettes to use. And probably half from sub-palette 3, but those are likely to be close by. I know you transcended the method, but I figure you found it first?
