Attention duelists! The official software for the world championship was released on December 06, 2007, but no one made a forum on it! So here we go!
There are 2 modes, Duel World and World Championship. Duel World puts you through 6 diffrent worlds of insanely restricted duels, while in World Championship you can classicly duel any characters you've unlocked or friends and rivals through Nintendo Wi-Fi!
As per usual, you may create your own character. But that's not the best part, there are more cards, packs, and a nifty new program where you can log onto Nintendo Wi-Fi and download 1 card daily.
