My super smash bros 3ds extra data stored on the SD card has turned into a question mark and it doesn't appear that I can delete it from the 3ds itself. I was wondering if there was a way to either recover this data, or figure out which folder this data is stored in on PC and delete it from there. I'm okay with losing this, and so far no other games seem to be affected.
Its also worth mentioning I wont actually be able to fix this for about 2 weeks. I just want to know for future reference.
