From my recollection, CPSII is wired just a bit differently than standard JAMMA. Again, from recollection, I need to add a AMP for QSound as well as an additional speaker (the cab currently just has one). I also seem to remember that my CPSII cab would not play standard JAMMA games correctly because the buttons wouldn't work indiciating the button's ground is different? Anything else I should know about? Is it possible wire the cab to run standard JAMMA and CPSII games?
 
The wiring is the same as for SFII in that it uses standard Jamma wiring. You would need an amp to have stereo sound but can run mono from the jamma harness. Only difference in wiring the buttons is that you use a different kick harness, other than that the top 3 punch/fire buttons should work with any game.
 
i just hooked up progear in my jamma cabinet and didn't have any problems. you can go into the test menu and switch between standard jamma mono and q-sound stereo. you might need a cps2 kick harness depending on the game.

does anybody know if you need to use the q sound amp, or can you use any sound amp for q-sound? i have a pc amp that i was using when i was running a playstation 2 in my jamma cab, and it worked fine. i tried hooking it up with the cps2 setup and nothing.

Did you change the settings on the board so it would output through the phono plugs? I believe you have to do this to get sound from those.
 
Yeah CPSII is JAMMA standard. I use my cab that is used primarily for CPSII games to test boards and occasionally play other JAMMA boards. I don't have a Q-sound cab, just a dyanamo, and yes the CPSII kick harness is the only thing I can think of that is CPSII dependent.
 
I think the kicks HAVE to be grounded to the ground on the kick harness.


This is not true. I have modified all grounds to run through the Jamma harness of my cab because I swap between CPS 1 and CPS 2 games and the kick harnesses I have are grounded differently.
 
Just chiming in here to agree with everything said above. You'll need a Qsound amp and an extra speaker. Kick buttons need to be grounded on the kick harness, not the JAMMA harness. JAMMA games should work fine in the cab -- I swap out a JPAC, JAMMA boards and CPS2 games in my big blue Capcom cab.
 
A handful of CPSII games use a fourth button off of the JAMMA Harness (like neo geo) and not on the kick connector.

Not true.... The ground off of the Kick Harness is the same as the ground off of the JAMMA harness. As long as the buttons are grounded from SOMEWHERE, it will work.

Maybe you need to rewire your big blue.

You have to make sure that you have it set up right... I can't remember what the exact settings are but it's a bit asinine. I think that you have to use the right TWO settings.

The motherboard outputs really really low level sound via the jacks. SO you have to crank it up to hear anything.

Any amp will work.The better the amp, the better results. I suggest using a small car amp.

There are some people that swear that the Q sound amp has some type of special circuitry, but I think it's a load of shit. Q-Sound technology is all on the Motherboard, not the amp. Remember that lots of non arcade stuff also used Q Sound, even some audio CD's.

It's just a spacial stereo technology. Simulating 3-d sound using two speakers.
