NEOGEO MVS PCB with 2Joystick ports on regular Jamma Cabinet

NEOGEO MVS PCB with 2 Joystick ports on regular Jamma Cabinet.

Hello,
I’m interested in buying a NEOGEO MVS PCB to play some MVS carts which I own.
I noticed that the 2 cart slot MVS PCBs have 2 joystick ports as well as the Jamma port and stereo output.
I own a regular Arcade cabinet with 2 joysticks, 2 sets of 6-buttons, a regular Jamma slot and one speaker (Mono sound) connected to the Jamma slot of the cabinet.





My queries are:

1. Will the 2 cart slot MVS PCBs work on my regular Jamma arcade cabinet (Both joysticks and Mono sound) if I connect the MVS PCB to the cabinet Jamma slot and leave the extra 2 joystick ports and stereo output of the MVS PCB unconnected?

2. Do the 1 cart slot MVS PCBs also feature 2 Joystick ports and Stereo output and should I get one of these instead?

Thanks in advance

Weeeeelllll....
I don't know exactly how the NeoGeo board is set up, but I know one big obstacle to JAMMA-standard.

NeoGeo has 4 buttons per player. JAMMA only supports 3 buttons per player. You need extra wiring, no matter what you do.

I have a 2nd Arcade Jamma cabinet with 6-buttons, wont it work on that without extra wiring?

1. You mean I will I need to solder extra wires on the NEOGEO PCB connectors to the Jamma interface on my 3 button cabinet?

2. Also, one more very important aspect!
Will I need a different power supply to power the MVS PCB on my regular Arcade Jamma cabinet?
I wouldn't want to burn it up!

Q: Will the motherboards work in a JAMMA cabinet?
A: They will all work, but are not 100% JAMMA compliant

Q: What does that mean?
A: The 1 slot boards are the closest to JAMMA, but have the addition of a 4th button. Some of the 1 slot boards have an external connector to run Stereo sound instead of the mono JAMMA sound.

It doesn't really go into depth of whether I'll need to do any soldering and add extra wires, or if it needs a different power supply?

From what I understand it will work, excluding the 4th button and the stereo sound on a regular 3 button Jamma cabinet.

However, it doesn't mention if it will work on a Jamma+ 6-button cabinet though?


Thanks in advance.

As far as I know, button 4 and stereo sound are the only non-JAMMA parts on the slot-1s. I don't claim to be an expert, though.

I'm pretty sure the Street Fighter kick wiring harness and the NeoGeo D harness are different, though.



I know more advanced boards get weird. But then, more advanced boards are better suited to a dedicated cab.
