So I got a used DSLite at Gamestop... Big mistake, the damn mic doesn't work and they'll just give me another damned used one if I return it (Already tried 3 of their used DSes All friggin broken in one way or another, or they have 50 million scratches! Also I got the extended warrenty, but I guess that doesn't matter) This pisses me off! What the hell can I do? Is there a way to fix it?
