I've been having trouble with the HSS kit I picked up recently. I followed the directions to a tee and also watched John's video on his install. The kit seems to work periodically. When the game is on attract it lists the high score board but they are all erased. Any suggestions?
You could have gotten a bad NVRAM. They are OLD. If you are POSITIVE you installed it correctly, and if the scores save sometimes, then I would contact the seller to see if you can get another NVRAM. You might have gotten a bad one.
