I have a Joust upright and a Robotron upright.
On Joust, the high score save works just fine. it'll save new high scores and all existing scores.
On Robotron, if you get the highest score it will do odd things with existings scores. sometimes one or two will disappear, sometimes all of them disappear.
I have tried the Joust CPU in the Robotron, with the same effect of flakey high scores. So it appears the problem is independent of cpu's or battery issues.
Which leads me to presume the problem is on the Robotron ROM board?
Anyone seen this before or have some technical insight about what is wrong?
The next step would be to pluck all the joust Roms and insert the Robotron roms. I'd really like to avoid that due to all of the potential new problems it introduces with sockets, chips, etc.
Thank you.
