GameCube – Game Boy Advance link cable

The GameCube Game Boy Advance cable (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.

Development
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", which would allow certain Nintendo 64DD games to connect to compatible Game Boy Color cartridges. However, the device was never released—interactivity between Nintendo 64 and Game Boy games was limited to those that supported the Transfer Pak, released in 1998.

Systems
The cable has one end that plugs into a GameCube controller slot and another end that plugs into the GBA's extension port. 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. When used with the Game Boy Player accessory, the Game Boy Advance system can be used to control any Game Boy game played through the GameCube.

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 do. It is also incompatible with the Nintendo DS family, as the original Nintendo DS and DS Lite's backwards compatibility for the Game Boy Advance does not extend to its accessories, lacking the necessary extension port.

Games
The following is a list of compatible GameCube games, with the corresponding Game Boy Advance (GBA) game or N/A if no GBA game is required.
