So i have a party zone I have been working on for a guy on and off. I have replaced the balls, rebuilt the flippers, replaced the ball shooter, replaced a bunch of broken plastics, new rubbers and cleaned everything.
One thing I noticed was it doesnt save settings, and it had batteries that looked a little rough, which i removed and I tried to clean up the best i could to prevent any damage. It doesnt really look like there was damage. I told him the best route to go is to get NVRAM, which will require me socketing the chip, not a problem, but i only own Stern Whitestars at the moment, so i would have to do the work on site and its not the greatest work environment for soldering.
We went ahead and tossed in new batteries, but the game still doesnt appear to save its settings. If there was damage to the battery area, i would imagine that would cause the settings to not save, but if there was damage to the battery holder area, would that matter if i put in NVRAM? I would think not, but Im trying to get some more info on that since i havent had this issue myself.
