Cube Link Advanced - GameCube

The Cube Link Advance cable connects the GameCube to the portable Game Boy Advance, allowing users to share information between games, access hidden areas, download minigames, and more. The cable can only be used with games designed to be compatible with this function. The cable is 6 feet long. One end attaches to the top of the Game Boy Advance and the other to an open controller port on the GameCube.
