Server shutdownIn early August 2006, EA closed their servers for multiplayer games, for the PS2 and Xbox versions.
Version differencesThe Gamecube version to make up for having no online play features two Nintendo related extras. The first is the unlockable boxer Little Mac from Punch-Out!! (NES) and the second is the complete game Super Punch-Out!! for the SNES.
