I am actually really disappointed with this game. Since the GBA games were so good, I was having high expectations of this. I was hoping for 3D models to appear in the game like in the cartoon. Well, I got what I hoped for...but they had the gall to change the game to some sort of English History lesson. Argh. It isn't even Yu-Gi-Oh TCG anymore, the game is entirely different from the card game. How did they think of that...
And it is still in the top 10...hello thousands of disgruntled 4 year olds
Sorry I can't help you. You could go scour the internet for cheat codes though.
