If you read about this, is a Dual Layer game for both Wii and PS2. Well, PS2 is having a "special" edition that has the Japanese voices, Wii only have the english ones. The thing is.. anyone tried to undub the Wii version? The only way to do that is take the sound files of the PS2 special edition and insert it in the Wii version. I'm trying myself, but i don't know how to open .cvm files (in PS2 game discs). If someone is interested, can be a great project to enjoy more this game.
