The Simpsons Pinball Party
Stern, 2003Hi
I have made sure I press start two times in order to have a 2-player game. When player two drains suddenly now player 3 and 4 is up ?? Why is this acting this way. I played a one player game just now and that went fine but that isn't always constant either. Any ideas, ?
Thanks
Matt
Sounds like a switch matrix issue. Go into the switch edge test and test all the switches. Make.note if any that do not register and which register several switches when pressing one.
Also post a picture of the top right area of the CPU board. The switch matrix input is to the left of the battery holder.
