So, I've been trying to get better at creating codes for games that are a bit obscure and games that don't really have any codes for it, yet. And I came across Pokémon Rumble U.
But the thing is, I'm having a hard time even finding the memory region that I need.

My goal is to be able to modify a Pokémon's moves, and the Pokémon itself.

Just wondering if anyone has had any luck with hacking this game, because I'm rather lost at this point.
Whether it's the memory region, a save editor, or any information at all, any help is appreciated.
