Quoted from cutlerkeith:However, while inspecting the game I also noticed that this sort of daughter board was wired into the reset circuitry. What is it? What were they trying to achieve? Anyone have a clue?
It's just a simple 555 timer circuit to substitute for the 3 pin PST518B. Maybe they didn't have the part or wanted to alter the watchdog timing.

Quoted from cutlerkeith:Awesome! Appreciate the response. I installed my new power supply board and the game booted up and works.
The only issue I am still having is when I plug in the GI to the power supply board the GI makes a increasingly quicker click sound while flickering the GI until the GI fades out. I am a little confused by this.
Not sure from your description, but it doesn't sound good. Perhaps post a link to a video of the occurence?
