Yesterday I tried installing SNES9X on my 3ds, I've put the .Cia in my Cias folder and put it back in my 3ds, but when I turned my 3ds on, my games and apps were not there anymore, and neither were my save files.
Then I put my sd card back on my pc and it was like this, I don't know what happened, I tried formatting after I couldn't find any solution online, and is still like this, what should I do to fix this problem?
