Games and 6700 question

[JustusIV]

I was super excited about 2 years ago when i first bought my 6700. I figured i would play some games on it, but i found out that when i have one button pushed and pressed another the first button was release. i found a program that was called something like 6700keyboardfix that made it work a little better but still does not allow 3 keys to be pressed at once. For example lets take a side scoller game that i wont name but lets say a plumber is the main char if i am holding left to run and hold B for the turbo if i then hit A it doesnt work cause i am all ready holding left and B. Anyways any input would be appreciated.
