I've had my Dsi for a few months now, and of course got a warranty on it. Even registered it and got the warranty extended. But the right shoulder button stopped working. And at first I considered getting a new Dsi, but already had saved stuff on it that I wouldn't be able to get back Plus I couldn't find the receipt. Then I considered getting it repaired, and am going to. I still have the original box it came in. So, in the event that something happens to my dsi that is beyond repair would I be able to get a new dsi without a receipt?
