Well fuck
The good news is I got MH4U and a bigger SD card
The bad news is I just fucked myself over on my downloaded games.
Apparently moving around data is a big nono. I didn’t know you were supposed to use a certain tool to move save files around instead of just copying over the folder so it seems like my back up saves are corrupted. That only affects my downloaded games though. So I have to start over on Pokemon Y, SMTIV and Smash. Neat. That’s fine though since it would give me an excuse to play Pokemon again and now I can have all my games in the same place instead of deleting and redownloading. But its best to just buy the cartridges.
