I left my Dsi charging on a chair and my sister dropped it. When I tried playing a game, it doesn't do as I want it to. The screen also lost a tad bit of color (I hadn'tnoticed at first). I don't have a warranty so should I trade it in gamestop or do they not accept them. I mean it's in pretty great condidtions its just that that fall might have busted something in the inside. What should I do, becuase I was close to finishing the game and I really want another one but I don't want to make my mom waste a lot of money on it (this would be our 6th broken ds/dsi -_-")?
