I have recently noticed that when i close my DSi on some games it will turn off. this happens more often when i use the AKAIO (1.5) firmware (i use a acekard) than when i use the official firmware a game i noticed this happen in the AKAIO is Castlevania Order of Ecclesia and on the official one i found castlevania Dawn of Sorrow does this as well. is there any way to prevent this from happening? thanks. if you need more info just ask.
