Hi, I have two different sd cards. Not sure if they are called scan disks or sound cards. But when I go to use it it says the device inserted does not work with that device. I have a 2 gig scan disk and it says the wii on it. Then I have a regular one that is 2 gigs. I have version 3.4 of the wii. Thanks for any help. It won't save anything and I never used it before. I've had it for like two years. I played the games but never bothered to save them.
