I just noticed something very strange about my DS's microphone. Not sure if it just started or I just never noticed before, but when the AC adaptor is plugged in, the mic won't work in games like Phoenix Wright and Brain Age. It will, however, respond in Cooking Mama and DiagnoSe. When the AC adaptor isn't in the mic works in all 4 of the abovementioned things. It's an easily solvable problem, I know; just pull out the adaptor. But it bugs me somewhat. So does anybody know what the cause of this strange problem is, and perhaps how it could be fixed? Thanks!
