Swap which characters share palette

As for ff3usme, as I recall that's a big negative. As I recall, it will only change the palette itself and the number of the palette from the battle palette list. Since the "map" palettes are set in event code its not practical to set them from there either.

As for OAM, has to be done manually. Pretty sure its only been mapped and remotely understood fairly recently ("recent" as in the last 5-6 years at least), to the general public.

As for confusing? Just remember to look at the individual pixels while editing. Don't matter how good or fluent you get, a wall of 5,000 bytes of hex makes sense to nobody.
