Pony Fantasy VI Remake

There's probably some creative ways to do this, for instance drawing the exact size of the box moulds in paint, and then overlaying them over the monster sprites in usme lol, this is an idea off the top of my head. Besides that, you can import your monsters into another ROM (obviously not all of them or at once due to not enough bytes), and then use that as a reference when editing your monster/formation/moulds.
