Play JAMMA games on MVS...

Well, I'm no electrical genius or anything but my MVS cab plays all Jamma boards by just plugging that shiznit into the Jamma Harness. Then you unplug the sound cord from the 4 prongs on the mvs board and plug them into the 4 prongs on your new PCB. I only have one other working PCB that I play very often- X-Men. The sound on the X-men board is adjustable from the dip, accessed by pressing a small button on the board itself... Next PCB i'll be playing is TMNT. 
Hope this info is helpful

If you have a true MVS cab with two speakers that is wired to the MVS standard, you can plug a Jamma board in and it will play and you will get sound, but only out of 1 speaker.
If you want to get sound out of both speakers, there are a couple of things you can do. One is wire it up like you mentioned, but I would not recommend it as you would have to redo it when you want stereo out of your MVS games.
I am working on a easy setup that will allow you to switch from MVS to Jamma to the 4 pin PCB connector and get sound out of both speakers for each one. Look for it on my site in the next week.

Briggs, the speakers are set up so the positives are on pins L and 10, with their grounds commoned. That means if you disconnect just one speaker bu leave teh other grounded, you CAN smoke a board. (I did that to an Altered Beast when I brought it over to play around with).
A better way would be to disconnect the speaker grounding. Setup an SPST switch to go back to MVs standard. This would allow both speaked to be in series, giving an 8 ohm setup which works well...

what i did was put phono plugs on each speaker.
then i got a 4-phono-jack board.
i wired the neo 4 pin connector to two jacks.
then i took the jamma mono, and split it to the two remaining jacks.
so its just a simple switching of phono plugs.
look for it on my site as soon as im done with the controls faq
