I've been FUBAR'ed the last 2 days with machine issues. 
Along with rebellion from the Wizard of Wor, my MV-1F Neo-Geo motherboard has just begun reseting somewhat continuously.
The "somewhat" part leaves me a little hope it's not too far gone.
I've been reading through Channelmaniac's repair logs, I feel a little bit more confident, but lacking the logic tools (it's very cool he has done this!!).

So... I pulled the cart slot off, and behold the battery is lightly corroded, not bad, but likely the problem (a problem at least).
After seeing this and reading the logs, I took a look at my 2 other Neo Geo's... dang, their batteries are also corroded.
I'm gonna look for basic stuff that corrosion could have caused, but beyond that I will need need to hire help on the repair.
===========
One thing I can do for all three PCB's is to install lithium battery holders in place of the old NiCd, but I need some help.
The holder is pretty straightforward, but where is the best place to put the diode to stop the charging circuit?
Also is it a CR2032 lithium battery OK to use? (3v vs 3.6v)
PCB's I have:
- MV-1F
- MV-2F
- MVH Slot4
not sure of the 4 slot version, has two boards.
Side question:
How to remove the black foam on the underside of the PCB?
What purpose does this stuff serve anyway?
