I have an m3i zero with m3 sakura 1.40 and the f_core 1.0 data in my m3i zero. When I start running a game , the game runs fine , but when I close my dsi it goes off. I have tested an original game to see if teh problem is in my dsi , but this problem did not occur. I would appreciate if someone would know what the problem could be . Thanks.
