Just yesterday, this physical copy of Animal Crossing New Leaf worked perfectly fine. Today, it refused to load past the bootup screen of the 3DS. What happened to it and how can I fix it?
It's not just on this 3DSXL either, it won't work no matter which system I insert it to (there are 3 3DSes in my home). Is my data lost forever? How do I fix the cartridge/rescue my data?
