Ah .. that isn't an MVS cart, but rather a JAMMA board in a box that looks like an MVS cart (was thinking of buying one at one point because the price was just too good).

Having said that, IIRC, it isn't true JAMMA, but wired like the Atomiswave system Franco B mentioned with a further swap of two of the ground connections for button 6.

So, it won't work in an MVS (especially not a 4-slot) or even a standard JAMMA cab.

Vandammes:

Ah yes I get it. Well this thing is going on ebay probally then :)

Cheffo do you have answer for my last question on how to connect a pc to a neo geo mvs?

Thanks!

CheffoJeffo:

You need to disconnect the MVS board from the harness.

MVS 4-slot isn't quite JAMMA, so you would need to rewire a bit.

htttp://hardmvs.com has info on the pinout differences.

BobA:

Some of the other multi game plugins us jamma for 4 buttons and add the additional buttons as follows.

* 1 - 302-in-1 Classic Arcade Games - Happy Fish 2 JAMMA PCB
* 1 - Button wiring harness for buttons 5 and 6
* 1 - Manual with dip switch settingsBoard includes button 5 and 6 wiring harness.
The Happy Fish 2 board wires to a standard 56 pin Jamma wiring harness. The standard Jamma harness also used for the Jamma 60-IN-1 boards only has wiring for four buttons. The harness adds an additional two buttons for each player and extends the system to six buttons. Note: The Happy Fish boards do no have a VGA output and only use the low resolution RGB output directly from the Jamma wiring harness. If you would like to hook the board to a VGA monitor see our CGA to VGA CONVERTER

BurgerKingDiamond:

If you have a regular Jamma harness there will only by support for 3 action buttons per player. If you have a kick harness on there you'll add 3 more action buttons for a total of 6 per player.

A 4-slot MVS board cannot be used directly with a Jamma harness. It will mess up the audio on the board. You can buy something like this:

It goes between the MVS mobo and the jamma harness.
