[quote name='forthenguyen']270 coins away, man. I'm getting in some Wii Play motion w/ controllers, if all goes well. Can you register the same game more than once if you get different codes? I also have two Nintendo Selects games that I haven't played yet.[/QUOTE]
You can only register a title once, regardless of the number of codes you have. There is an exception if they re-release a game as a "hits" version. These are usually recognized as a different game for registration.
