Hello,
A few days ago I made the mistake of formatting the system memory when I was trying to just format the sd card. I made a backup of my SD card and was going to just port everything over. I've done that a couple tmies with no problem. Now that I've reformatted the system however, when I port over the old data I get an error that the system can't read the software on the sd card.
Is there any way to transfer my old mii plaza data to the "new" system? I worked so hard on it, I have so many countries and puzzles unlocked. Hats and find mii 2 progress. I would hate to lose it all.
