I have a Mame cabinet that I want to play all of the Hyper Sports and Track & Field variations. Hyper Sports works like a champ but Track & Field is weird. When you tap both of the buttons you can only get up to about 850 or so, but if you tap only one button you can get up over 1000. Why is it cancelling itself when you tap two buttons quickly? This happens the same way on two different cabs so I know it's not the buttons.
