I got myself Tomodachi Life for the 3DS the other day. I bought it used, but the seller told me the game was only used as a in-store demo unit and is 100% ok. I got the cartridge, the box, all the stuff. But to the point. When I try to play the game, the first thing I see on the screen is a notification, that the save file is corrupted and will be deleted. This happened the first time I played the game and it's happening every single time I try to save after making a new file. The game doesn't give any error while saving. What I tried so far, nothing helped: I played the game on a 3DS, 3DS XL and n3DS, The problem shows on every console. I formated my systems SD card clean. Tried with 2 SD cards. Remove the saved data completely with A+B+X+Y and start a new save. I downloaded the patch for this game from e-shop. Checked if the cartridge was fake or faulty - everything looks ok and legit. Import the save from the demo version. It imports the save, I can play the game, I can save the game, but after I turn it off and on again, the save is still corrupted... Any suggestions what to try? Is it even possible to fix a error like this on a cartridge? EDIT: Oh, I forgot... It's PAL version and no, I didn't attempt any hacking, save dongling or anything like that. My consoles are all newest soft, never modded nor hacked.
