The GameCube Game Boy Advance cable[2][3] (DOL-011) is a video game accessory manufactured by Nintendo which is used to connect the Game Boy Advance (GBA) handheld console to the GameCube (GCN) home console.

Depending on the games it is used with, the cable may facilitate transferring data between related games, unlocking additional content, or turning the GBA into a controller or second screen.

[4] The concept of a cable that allowed for the transfer of data and second-screen gameplay was originally conceived for the Nintendo 64 as the "64 GB Cable",[5] a device designed by Marigul Management which would allow certain Nintendo 64DD games to connect to compatible Game Boy Color cartridges.

The cable is compatible with the GameCube and the Wii on the console side; and the Game Boy Advance, Game Boy Advance SP, Game Boy Player, and e-Reader on the portable side.

Because the Game Boy Micro has a differently-shaped link port, the official cable does not work with it, but enthusiasts have been able to hack together homemade versions which does.
