Hi guys! Have anybody tried playing FIFA 08 and put it in Sleep Mode? I tried mine last night and after 5 minutes, it totally shut-off. This morning, I tried to isolate the problem and put other games in Sleep Mode (Brain Age 2 and Metroid Prime Pinball), it didn't shut-off after 5-10 minutes. I don't know if the problem is on the R4, DS, or the game itself. Hope to hear some feedbacks from you guys. Thanks!
