Since I bought both my 3DS system and Animal Crossing New Leaf retail copy in July 2013, it crashes rather frequently. At first my character would walk nonstop in a direction and I couldn't press any other button, than it would freeze completely, or the error message saying that the system will be restarted, and just frequently (like, on New Year morning, happening for the second time yesterday) the game would continue working apparently properly, but the buttons would stop responding, except for the Home button and the Power button. And after a year and half, I've grown really, really tired of it and would like to know what to do.
I would appreciate and be really grateful for any help on how to solve this.
