I have a backup of my SD card from March 2015. On that SD card I had data for my Animal Crossing New Leaf game. I've also found the specific folder inside "00040000" where the data is located. My only way of accessing these folders is with my PC as the ID of the folder is no longer linked to a 3DS because I formatted it after the backup. I formatted my 3DS yesterday because I was setting up CFW which I now have. Meaning the backup I took in March has totally different IDs than what I have now. Is there any way to get back my old save?
