No biggie,

just wondering if anyone knows which chip (along with the batteries) is responsible for saving settings.
I have two Sinistar boards;
one with issues, but when it works it saves settings flawlessly,
and another that works great but will not save any settings even with fresh batteries.
going through the setup every poweron is getting old.

Thanks guys

Purchase a 5114 RAM chip from arcade chips and replace the one on the baords that does not save high scores. Use a socket.

WASH, recap, replace all headers, and swap out the RAM to 4164 RAM on the board with intermittent resets. Lithium battery kit it while you are at it.

Thanks bro,
I just saw your reply.
In fact, I just got back from my arcade.
I swapped all of the 5114 from my intermittent reset pcb
(I also had some spares from my last Zookeeper pcb repair episode)
into my no save settings pcb
and it seemed to work.

There were a lot of 5114's and was hoping someone knew which one narrowed down
handled the settings save.

Looks as though I am out of the woods for now.

Thanks for your time and advice.

Glad to hear things worked out for you. Just for clarity sake: the 5114 RAM is a CMOS RAM that is soldered into the board near the CPU. This is what has broken if you cannot save high scores.

The 24 socketed RAM are most likely 4116 RAM. Best practice these days is to upgrade the 4116 RAM to 4164 RAM with a power adaptor. These are the first suspect in instability.

I am confused here. There is only one 5114 CMOS RAM IIRC, and you say that you have changed out all of them?

Are you referring to the 24 - 4116 socketed RAMs? If so, that is not going to fix your problem, and the settings will be lost again.

If you have a switching power supply in this game, there is a 99% chance that is what is causing your lost settings.
