I've had a persistent problem with the memory on my Sharpshooter, seems to lose its high scores and displays a bunch of garbled stuff on the score displays when showing the high score. Resetting the high score and zeroing out all the settings straightens it all out, but after leaving the game off for a while, it inevitably loses its memory and needs to be reset to display proper high scores. Everything else works fine, and I've lived with the issue for a while since it never really bothered me. I'm getting ready to set it up at a buddies place and decided to fix the memory problem first since it's gonna be their only game there (for now... ) any advice?
The mpu on this game has been serviced by the coin op cauldron, and a memory cap was installed. I've tried different 5101 ram chips but for some reason the game will only work with the ram chips that it came installed with. I might have to reach out to the coin op cauldron to get this sorted, but thought I'd ask here in case anyone has any suggestions to run down first. Thanks!

Quoted from Robotworkshop:

Just keep the new one off the board! Your best option is probably a remote battery holder using 3 AA non rechargeable batteries with a 1n5817 diode inline to prevent them from charging. That is a common option used on Gottlieb, early Bally, and Stern that used rechargeable batteries originally.

Many thanks!!! I didn't realize viperrwk put out videos for these repairs too--that video was sooooo helpful! Pretty neat the way these boards work. I'm guessing at this point either a bad volume pot or a problem with one of the amp chips. I replaced the amp chips a while back, but I'll have to double check my work on them.
Also--it appears we have an 8 ohm speaker installed in the game, should I plan on swapping it out for a 4 ohm? It's worked fine with the 8 ohm up till now, but I'll swap it out if it's possibly causing any trouble.
I'll post back when I get a chance to troubleshoot the board and share my results.
Thanks again--that video was extremely helpful!

original as far as i know

Quoted from desertT1:

I am considering it, as even off the game the memory caps are depleting faster than I would have thought. I’d like to see if there is a reason why my MPU is draining the battery that came with the game (not original) and these caps in case it can clear up any issues I don’t yet know about.
