When I close my DS instead of the light going on every couple seconds, it goes on and off quickly, and when the light goes on, the screens go on also, then when the light goes off, the screen goes off. What's causing this? And why can't I undub Rune Factory 2? And why does it hang occasionally in Rune Factory 2? And my last question, do I have to keep to cheat on for CT for the entire game, or just that one part in the Fair?
