In Yugioh WC 2008, why won't my passwords work?

Question

Also, could someone please post the numbers to these cards... polymerization, Dark Magician, Jack's Knight, Raigecki, Swords of revealing light, and exodia pieces, if available, or God cards even....Thanks

Answer 1

you have to have 80% of the pack unlocked. then you have to have enough dp

Answer 2

if you enter a password for a card you must have the card first so if you put in cyber dragons password and you dont have him already then it wont work.

Answer 3

you have to have the pack that actually has the card in it. For the card numbers, just go to gamefaqs, type in the game, then click on the cheat link.
