As a whole console, it is the successor of The Nintendo GameCube.
There is an accessory you need to buy called a game boy player. It clips onto the bottom of your gamecube and has a slot for gameboy advance games.
You cannot play Gameboy Advance games on a Wii, but you can on a Gamecube.
Yes the Nintendo Gameboy Advance can be connected to the Gamecube through the use of a link cable which can be purchased.
to connect the the special island, you need a gameboy advance and a game cube + game boy advance cable.
Depending on the game you are using, the cable might have to be put in a certain GameCube socket. Make sure that the GameBoy Advance has no game in it unless you need it.
The Gameboy Advance to Gamecube link cable provides connectivity between the two consoles for certain game titles such as Animal Crossing.
