So I finally bit the bullet, updated my emuNAND to 9.5 and downgraded my 3DS XL to 4.2. Everything seemed to be working fine until I started to boot some ROMs. They were all detected fine, and I started up a game. Played it for a little while, saved it, then exited the game to the home screen. After this, I went back into the game, and it claimed the save data was corrupted. I opened a different ROM, and the same thing occurred. This has happened to me with 3 different games. Any ideas? The SD card in the machine is not locked. Both games that had been opened previously, and games I had never opened before both claimed to be corrupted.
