 The PlayStation 2 and GameCube versions of this game differ from each other  in a few ways. The control setup is different, for starters (all the games on  the PS2 version have controls similiar to Mega Man 8, while the controls on  the GameCube version are like a reverse of the NES controls). But the most  noticeable difference between the two is in the special features. The  PlayStation 2 version includes an episode of the Mega Man cartoon, while the  GameCube version features a G4 special about the history of Mega Man.
