It should be possible to edit the save file of Pokemon Rumble (WiiWare)

Pokémon core series save editor

Unrelated/unconnected games that do not store fully formed Pokémon data are not within the scope of this program, as there is zero reason why it can't be a standalone program. None of the data structures are related to those of the core series games.

Same argument as "why not support editing Animal Crossing saves within PKHeX?" It's a separate set of concepts, and should be a separate project/program with no direct ties to PKHeX.

If there is no save editor for the game you want, research and develop one yourself/with others.
