Hi, I see your comment about solving your "LOADING..." issue. I have a R4 card for my son that works perfectly fine so I purchased 4 more cards (from a different website) for my daughter and friends and none of them works. I get the Loading issue on all of them. Card almost seems thinner and like it's not making a connection with the DS! That might sound crazy. Curious, what did you do to fix your problem.

Thanks
