Pony Fantasy VI Remake

Not sure if I'm reading everything correctly, but I do recall changing palette 7 (the colors, not the palette number used) and as Drakey said, the battle sprite didn't change. While loading the overworld palette would have been the logical thing to do, it kinda seems like they are loading something else.

A quick sloppy test might be to change the browns of some normal battle palettes to something that would stand out (possibly import a full palette of neon green) and see if it has any effect in battle. Would have to check the battle palettes one by one though (hence the reason I said sloppy test), the result would either show it is in fact using a battle palette, or hint that its using something else.
