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
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. The cable 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. In July 2021, the team behind the GameCube
emulator Dolphin announced the integration of the Game Boy Advance emulator
mGBA into the program, allowing a Game Boy Advance emulator to run within Dolphin simultaneously to simulate GameCube-GBA connectivity. In addition to supporting transfer of data to and from emulated GBA titles, up to four Game Boy Advance instances can be simultaneously active in Dolphin at once, making multiplayer in games that require the GBA such as
The Legend of Zelda: Four Swords Adventures and
Final Fantasy Crystal Chronicles viable within Dolphin locally and via netplay. In contrast, GBA connectivity is not available in Nintendo's official GameCube emulator for the
Nintendo Classics service on
Nintendo Switch 2.
