Does any one know how to beat the expert cup so I can use the password..

You have to beat the beginners cup and you will eventually get an e-mail inviting you to join the expert cup. The train station will appear and you will go to the second town. Find ishizu ishtar and defeat her three times. This will unlock yami bakura. Look for bakura at night in the second town. He will say hello and tell you he has had enough dueling for the day and that he will go home. Sometimes he will leave, but keep finding and talking to him and he will become yami bakura. He will challenge you to a shadow duel. Be sure to look out for his dark necrofear and destiny board cards. Once you win, he will laugh and tell you he had fun dueling you. You will unlock the expert cup finals. It is like the beginners cup, only more difficult. You will duel rebecca twice, then you will watch a duel between joey and yami bakura; you will be watching from joey's side. Joey will lose, and due to a glitch in the game, the loss will count against your record. Somehow joey gets hurt and ends up having to go to the hospital and you will duel yami bakura twice, then yami yugi. Once you win the cup, you can use the password machine, howver, you have to have the get card list that the card you want is in, or the machine will not recognize the password. You will be invited to a private party at the kaiba mansion, but you will not be able to go in until the night of the next day. Noah will appear and after a long dialogue, he will tell you to beat the big five. Go aroung the map; they will all be level 5 or 4. Beat them all and you will go to noahs base. You will find mokuba being possessed by noah and you will duel him (he is no harder than normal). Then, noah will challenge you as himself. Once you beat him you will be challenged by gozaburo.
