I have been getting RAM errors on my Galaga more and more lately. 2H and 4L. Getting a lot of resets. Also getting dimness on an off, right before it resets.

The game has the original power supply, not a switcher.

I was thinking of replacing the RAMs. How many and what kind of RAM does this game take?

Any other thoughts on the issue?

Thanks.
 
I had alot of the same. Check your +5v across cap C1... you'd like it to be about +5.2v. If it's low (probably will be) it can create all sorts of problems like this. Then, save yourself alot of time, effort & frustration and remove the original power supply board and install a switching PS.... you'll be glad you did.
 
I checked the voltage and it's low. I have a switching power supply and harness I bought a few years ago. Will put that in and see what happens. I bet it works. I was able to adjust the existing power supply to get just a little bit more out of it and the game is not resetting any longer.

Thanks for the assistance.

Galaga lives for another day.
