So I visited the arcade of someone I have come to know and while taking a look around and playing a few games, I stumbled across this screen on a Frogger:
Not exactly playable, if you catch my drift. Went over the usual stuff, power, reseating, etc. Voltage was a little low, and the power supply could use some maintenance because of a bit of ripple. But was able to get it back up again. When it booted, it booted into an odd screen and I realized it had some kind of HS kit in it. This was actually nice because it included a RAM and ROM test that showed everything passed.
Went into the game and coined it up to play, and saw this:
Pretty sure that we do not want that many lives per game. Seeing that this was a pretty strange issue, I thought to reconfigure things in the HS kit. After readjusting things to 3 lives per game, saving the changes and restarting the game:
Much better, eh?
After fixing something, always be sure to actually try to play it and make sure everything is working right.
