So I've had this for about a month, but I'm working on fixing it, however, it hasn't gotten anywhere. Here's what happened: I set up my 3DS XL (9.2) with an emuNAND. Knowing that the Format Emunand option would clear my SD Card, I backed up its contents (Games and save data), as well as the newly-created NAND.bin file to a folder on my laptop. Then, once the format was complete, I copied back the game/save data to my SD card. However, none of the content read on the newly-formatted SD card, which means that all the games on it are essentially useless, taking up space. Not to mention all the save data (Including 110 hours of Pokémon X) are all gone, with no reason as to what happened. Both sysNAND and emuNAND fail to read it at all. Has anyone had this happen before? None of the data was modified or anything, yet it all fails to read. I still have the NAND.bin and contents of the SD card prior to the whole thing, so I have at least some form of way to restore all my game content. Question is, how can I go about doing it? Edit: I'm beginning to believe that it has to do with how the SD card is formatted. Different formatting has the system read the SD card differently. That, or else the 3DS just gave up on itself.
