i have nintendo dsi it works just fine till the day when i was playing yu-gi-oh 2011 game and had to eat so i put my dsi in sleep mode (close the cover) the game was still running and when i came back i notice that the picture in both screen got pixeled (like i can see the small pixels so clear ) first i thought it is a hardware problem but how can be possible in both screens in the same time . anyone please help me solve this problem i have 500 game on ds but now i abandon it cuz i focused in pixel more than the game .
