I mentioned the power supply on Star Wars that has very high potential issues on the post above.

Anytime NVRAM is installed, batteries get removed. I remove the battery holder to prevent accidentally installing batteries. There are only 2 contacts on this SW battery holder at the bottom right 2 battery connections. I think you can cut those flush with the board. This way you don't have to take out the board.

The red highlighted part in the picture shows the old RAM is located just under the Game ROM(s).

Just inspect the connectors on the PBB and push on all the fuses gently to see if any fuse holder caves. I hope all are good.

xpin board...sweet. Nothing needed then

Excellent. Once you install NVRAM in SW, you should be good for a long time.

I enjoy helping.
Tomorrow's thoughts, as it is already past midnight. My eyes are burning.
Mainly connectors are about the only common issues with WPC games other than acid damaged MPU boards.

LOL. Been using BBU caps for 15-20 years now and no, never been shocked and never had one "explode".

There are a bunch of acceptable options from cordless phone batteries to NVRAM.

"Explode"... how dramatic! LOL. Thanks for the chuckle.

I never said shocked, not at this low voltage.
Visible failure is not always immediate.
Capacitors leak just like batteries.

This includes BBU capacitors.
One overcharge the case ruptures and now you have corrosion damage.

Yes, capacitors can explode, watch what happens in a Early Bally Solenoid Driver Board regarding a short circuit. I have photos somewhere of the person who severely burned his skin and had temporary blindness in one eye. He was #! $@Inc around with the power on and not playing attention.

Owners should not use capacitors in place of batteries.

you do NOT throw batterys in the garbage can....

modern batteries actually can be thrown in the garbage

Yes, Cap's explode and they DO shock as well, even at low voltage, don't be fooled. Ever taken apart an old-school disposable camera? The flash is powered by a super cap, hooked to usually 1 or 2 AA or AAA batteries. That's 1.5v or 3v, respectively. The CAP will give you a very sharp shock if it's charged up and you touch the leads. I have experienced this, it hurts. 5v can still shock you, it's not neccesarily the voltage you have to be concerned about, it's the sudden amount of charge that dissipates over a very short period of time. High current can be just as dangerous as high voltage. Not saying it will kill anyone @5v, but it can hurt!

Years ago, all recyclables and batteries were collected separately around here. Now, everything just gets tossed in together and (I'm assuming) sorted at the trash facility. Or it all just gets burned. I'm not quite sure.
