This is the second one I have put together, I think the other one is in Australia. Dremeled off any corrosion /oxidation on the battery contacts and bent the tabs that hold them in place so they dont wiggle around which ensures better battery contact. I also cleaned all the gameplay contacts. See photos to see how it used to look.
There are oxidation stains on the back where paint might have fallen on the game actually preserving the original white color of the game. They games were originally white but after 30+years they have all started to turn a tan color.
