M92 games that might use the M92-B-G PCB: Dream Soccer '94, Gunforce 2 / Geostorm Ninja Baseball Batman Superior Soldiers / Perfect Soldiers Irem used other model B boards for these games too, so you have to check and specifically see if yours is labeled M92-B-G.

Sign me up! :thumbsup:

The resetting means that the Watchdog circuit is likely triggering somehow. Under normal circumstances, this happens when the CPU crashes. Try the following: 1) Measure the 5V rail on the JAMMA harness and make sure the board is receiving 5.0V . If so, try increasing it slightly up to 5.05V or...

I'll pull my boards out this weekend and do some measurements.

Don't need one, but kudos for being willing to put in the work for the folks that want one. :thumbsup:

I’ll get my order in after I get paid on the first. I just moved into a new house this weekend so it’s been an expensive month!

If you don’t want to mess with surface-mount soldering here, you could trade the mask ROMs on your MS5 CHAFIO PCB with the same PCB from a working donor.

NEO-CMC goes bad on these carts all the time. Same thing happened with my Metal Slug 5 cart and I had to pull a donor chip off a King of Fighters 2003 cart.

Sounds like you've done everything right to me. Perhaps the MiSTercade doesn't support the "Analog IO v6.1 / Digital IO v1.2" that's referred to in the requirements for the adapter? What do you think @misteraddons ?

I did some reading up on the Y Board hardware as well as firing up G-LOC in MAME, and I learned a few things that should help with your diagnosis. First of all, G-LOC has a Self Diagnosis mode that you can load up through the Service Menu. I highly recommend starting there if you haven't run it...

It’s hard to tell from your pics, but is the horizontal lines through the entire display or only certain tiles? If it’s only certain tiles then a ROM issue is likely the culprit. If the lines run through the entire display then it’s more likely an issue with line buffer RAM. Schematics for the...

Is your earth ground wire connected from the RetroArcade PSU to the wall outlet? Also, does your monitor chassis have an isolation transformer installed? https://www.arcadepartsandrepair.com/store/cabinet-parts/power-supplies/monitor-isolation-transformer-120v-output/

Are you plugging the adapter into the User I/O port? It won't work if plugged into USB.

Fantastic!

That AvP hurts to look at - you’ve got some serious repair work ahead of you, but it sounds like you’re up to the task. Good luck! :thumbsup:

I’d like one of the audio merge kits please.

Odd - I removed the JP1 jumper and left the BIOS EPROM installed in the socket and it hasn't reflashed the BIOS on me. Interesting.
