All controllers, Game Boy Advances, and Game Boy Advance SPs connected to the GameCube are recognized as the same player. This allows a sort of co-op mode for games that do not normally have it (this was most likely not intended by Nintendo). Furthermore, allowing for multiple controllers recognized as the same player allows for simpler and more comfortable play of single system multiplayer Game Boy Advance games, such as those found in "Mario Party Advance", in lieu of up to four players holding one Game Boy Advance unit.
