The Neo Geo hardware was an evolution of an older SNK/Alpha Denshi M68000 arcade system board that was used in Time Soldiers in 1987, further developed in the SNK M68000 hardware platform as used for P.O.W. Prisoners of War in 1988.

Anyone can enjoy playing Neo-Geo MVS games at home with a supergun (like this), or a good arcade cabinet. Sometimes though setting up the supergun is inconvenient, and the cabinet may not be an option to some people. Emulation is always a fallback, but nothing beats the real hardware. Another solution is to convert the MVS boards into a console. All that’s needed is some planning and a few parts.
I was asked to do a consolised MVS conversion for a customer. we discussed building a basic RGB Supergun from scratch as he wasn’t satisfied with the video quality for his existing unit but settled on the conversion.
How does it work

Simply all you need to do is recreate the basic supergun components within the MVS case. Power, Video, Audio and Controllers.
Power
The one slot Neo Geo arcade Jamma boards make use of DC 12v and 5v power. The 12v powers just the audio amplifier, while 5v drives everything else. The Audio amplifier can be switched to work on 5v with a few modification found here. Basically all that needed is to isolate the 12v line and pass the 5v in its place.
The power supply I selected is a 2.5A 5v unit, this is plenty for the one slot Neo’s. I’d also need to install a switch and fuse for safety and a LED to indicate its running.
Video
The video is tapped off the Jamma edge connector and runs to a 8pin DIN socket. I wired it to match the wiring for the Neo Geo AES and CD consoles so the same RGB Scart cables can be used.
Now the power and video lines were attached I could start testing. Below you can see the video test screen and game play from King Of fighters 2003.
Controls
Linking up the controller ports is simple but very fiddly. I have used DB15 connectors so that original Neo Geo CD or AES controllers and joysticks can be used. All the wires are linked up below the jamma edge along the resistor banks.
You need to just connect a wire for each of the player inputs from the board to controller ports. Its helpful to have a copy of the port pin-outs handy. I mounted the controller ports on top of the case. The small amount of plastic on the sides would also work, but you have more chance of breaking the case while cutting/drilling.
Audio
Jamma boards output ready amplified audio ready to connect speakers. To use the audio on a TV we must tap the signal level audio before its gets to the OPAmp chip. I also had to make a small amplifier to raise the line audio to the level needed for a TV or external amplified speakers.
The full diagram and singal tapping info can also be found on JammaX. This circuit can be used on all the 1 slot MVS units, just with different tapping points. The audio can be outputted to the AV port, jack connector, or even both.
Finishing
So the final product turned out very well and works great.
There we have a quick and convenient solution to playing MVS games on a RGB TV.

Hi guys, I just picked up an MVSU4, my first neo cab. I'm not sure if I'm just an idiot or if there is a problem with my board. I fixed a sound issue, but the game select button does not work. I don't have a credit button so I play games on freeplay. If I boot up the game in freeplay mode, is the game select button disabled? I thought you could just turn the machine on, and press select game while it is in attract mode, correct?Neo Geo Mvs 1 Slot Manual

I checked continuity and it seems fine, but just in case I jumped pins 26 and d, select up and select down to ground with no effect in freeplay mode. Any ideas where to look elsewhere? Right now I have to wait for the demo mode to switch over to the game I want to play.edit: Also on the bottom board there is are pins for different harnesses labelled 1P, 2P and EL. I only have a harness that fits 1p or 2p so I have it plugged into 1p, but what are they?
