Its true. Nintendo has made Ocarina of Time for The Nintendo GameCube. Nothing much has been changed, except the graphics have been made a little bit neater due to the GameCube's power and its hi-resolution.
It came as a surprise to Japanese gamers who pre-ordered The Legend of Zelda: Wand of the Wind. The disc comes with Ocarina of Time, adjusted to the GameCube controller, and Ura Zelda, the unreleased version of Ocarina of Time but a little different and harder.
Nothing has been announced for North America or anywhere else but most likely we will see the same thing. The disc is free, and contains the 2 games and videos's of Zelda games.
