Hi ya,
Have a Stargate. I replaced the power supply and the battery back up on the CPU. All voltages run and register correctly. However... regular high scores (initials only) save from boot up to boot up. The main high score with the longer 20 character text will not save, and will revert back to what ever the #2 was without the fancy 20 character message. Same with the "Custom Welcome Message", it will just revert back to the Williams Presents message. Bad Rom somewhere? Did I maybe miss some battery lead somewhere? Any help is appreciated. Thanks!
 
Why did you replace the power supply? Did you replace it with a switching psu? Those knock the voltage out too quickly and can keep the nvram (5114 chip) from being able to backup/store info.
Does it have the 4164 ram mod?

Either rebuild the original linear power supply (I like this option) or ditch the entire battery backup system and install an nvram backup. Actually, I would do both.

Stargate saves the all-time high scores only...

The high score of the day is the one that allows the long name.

Wouldn't be hard to hack to code to have it save that too though.
