I don't know if anyone else has had this problem. It's an issue I've had with my 3ds and the reason I had to buy a new one about a year back. For whatever reason my 3ds cartridges would get this sort of sticky residue on them that made them come out really slowly and botregister in my system. Usually I would have to take it out and put it back in several times before it would read it, an I usually had to clean it to. It got to the point on my first 3ds where it stopped accepting cartridges altogether. Has this happened to anyone else, and do you know what might be causing it?
