Just to let you guys know, I'm working on this WiiWare undub. There's a final trick I'm trying to figure out, but I'll publish as soon as it's done.
By the way, this undub is unlikely to happen any time soon. Even though the U.S. version includes the full voice bank from the Japanese game, the language options seem to be hard-coded into the dol itself (masked in the wad as 00000001.app).
