Query: BRAIN FRUSTRATION!

First of all, I do not have an accent or any kind of speech impediment. The only language I have ever spoke is English. BUT, the microphone interpreter on both Brain Age 1 and Brain Age 2 are terrible!! It is MOST frustrating when the mic misinterprets your answers and counts them as incorrect!!! I thought that there might be an improvement on the 2nd Brain Age, but couldn't even get past the "rock, paper, scissors" without the same problem. I much prefer Flashfocus or Brain Boost! Maybe it's the mic on my DS Lite. Oh by the way, my two teenagers ALSO have a problem with the microphone (and my daughter uses her own DS Lite)! Weird!! I am at the point of getting rid of the games just to recoup some of the money that I put out for them!
