I recently ordered a SanDisk 32GB microSD off of Amazon that isn't working properly. My sister literally likes every DS game out there, so it's basically full. I have a 16GB card that's a little more than half full and it works fine. My acekards are both updated with the latest firmware, so I'm not sure what's wrong. When I put only a few games on the 32GB card, everything worked fine. Is there a limit to the number of games or the size that can be on a certain card? Thanks for any help.
