So, I was using a save data manager in the Homebrew launcher on a New 3DS XL, I was going to back up my save file, but I accidentally hit "B" instead of "A", and it restored an OLDER save file instead of backing up the newer one. Now, I get an error saying the save file can't be used when I load my game. I know I could erase the save file, but is there another method where I could access the save file using a code of some sort?
