AFAIK Link is canonically left-handed, but since most people are right-handed, Nintendo mirrored the entire game so the motion controls would be easier to use on the Wii version. The GC version is therefore the correct/original one, while the Wii version is somewhat bastardised for the sake of waggle.I thought it was done to not make the GameCube version feel like the Wii version with the same map layouts.
