ok i got 2 weird problems after i let my friends use my ds: 1. Right and Down buttons are slowly stop workin (mostly right) i gotta like push it very hard for it to work. 2. Sometimes when i close my DS when a game is still running, it would start flashing and not go in sleep mode. Sometimes it even turns off. any suggestions? for the mean time, i'm playing Stylus only games, which for now is Legend of Zelda, Advance Wars, and it's a wonderful world.
