i'm trying to play against a friend for tetris party. do i need to register her wii console AND register her friend code in tetris itself since their two different codes? when i enter her friend code in tetris, it just keeps saying registering.
You only need to register the game code to play against each other. The console code is only for the message board. Sometimes it may take some time before the codes register each other (or however you want to say that), it can be delayed a bit instead of immediate. Make sure you both have registered each others codes and they should link.
