I’ll start by saying I don’t know a lot about newer machines. Most of my experience is on 80s-90s machines. So this is probably something easy that I just am not familiar with.
The kiss LE machine I picked up will not save settings. I change it to free play and play it. Then turn it off and the settings have reset. I changed the 2032 battery but it didn’t help. I noticed that there is a Game memory card but I do not know if that is the culprit or not. Any ideas?
