Well considering the Wii is backwards compatile with the GameCube, you can buy the Wind Waker, Four Swords Adventure, and Ocarina of Time: Master Quest. For the GameBoy SP, you can buy Four Swords and Minish Cap. They also ported The orginal Zelda and Zelda: Adventure of Link to the Game Boy Advance. There were 2 Zelda games for the Game Boy Color, called Oracle of Seasons and Oracle of Ages. For the orignal Gameboy you can play Links Awakening. Since you can play Game Boy games on an SP, those are playable. For the DS, you can buy Phantom Hourglass. So there are 11 more Zelda games you can currently play.
