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.
