CAPCOM CPS2 X-Men vs Street Fighter “B” Repair:

I had the opportunity to buy a few broken arcade PCB at some good prices recently and snapped a couple up. The first one was a Blue (ETC) X-Men vs Street Fighter:

This was listed as not working and wouldn’t display any image but for £45 I thought it was worth the risk.

It arrived promptly the next day and indeed when paired with my A board it did nothing.

So I needed to open it up using a T15 Security Torx bit, but first I had to remove the original CAPCOM tamper seals to get to the screws:

This implies that this CPS2 “B” board has never been opened up before.

I tested the battery with my multi-meter and it was reading at a completely dead 0v.
Thankfully it did not appear to have leaked at all and no trace damage was present.

I de-soldered the battery which was dated April 1993:

Usually I would now replace the battery with a new LS14250 axial lead battery and then reprogram the security key with my CPS2 InfiniKey as I like to keep everything as original as possible, however I did not have anymore left on hand so instead I soldered in the InfiniKey with the correct jumpers soldered.

Since this is a B-4 board you have there is no header to solder to so an alternative mounting point is used and you have to add two wires for Ground and 5v to power the InfiniKey:

A quick test:

That went well!

Also I love this sticker that is on the case:
