I've had an Alien Star for awhile now and have never been able to get it to boot. The other day I borrowed a working MPU from my buddy, swapped it in my game and now it works and plays. However, the pop bumpers are not working correctly. The right and center both fire at the same time, no mater which of the three are triggered. The left one does not fire at all, but can fire the other two when triggered. Looking around underneath it looks like some wires were added at some point (yellow and grey) and some wires were cut. Does the wiring look correct? Any reason for this? Any ideas on how to fix?
