Is it possible to use a GCN controller to play Wii games? What about vice versa?
There is still some confusion about whether or not this is possible. Masahiro Sakurai, director of the forthcoming Wii fighter Super Smash Bros. Brawl, said that the game would be playable only with a GameCube controller – not a Wii-mote. (The title will very likely also, if not solely make use of Wii’s classic controller.) However, Nintendo executives have repeatedly stated that GCN controllers will be incompatible with Wii games. Backing the latter up is The Legend of Zelda: Twilight Princess, whose Wii version is only compatible with the Wii-mote and whose GCN build is only compatible with the GCN controller.
