Hey everyone!

I just fixed the monitor issue with my standup namco cabinet it is a baseball game called "Great Sluggers" - The problem's now are

1) no sound - I havent really looked much into this

2) Game play - I found the switches near the coin mech that are Labeled Advance, Auto/Manu, and High score reset. I tried depressing the automatic/manual button into the locked down (manual) position and tried playing the game. I'm not sure how to tell whether or not the game is in automatic mode or the proper procedure for changing the mode setting.

Also I have been unable to confirm if all of the controls are working properly as i have not yet been able to play a game. It will intermittently accept quarters and allow you to select teams but from there usually auto-selects everything else.

When I think i am playing the buttons seem unresponsive, so I am unsure as to whether or not they work or what the game controls are...

3) I want to convert this Cab to a Jamma Multi-game. Is there any preparatory info I need? or can is it basically just plug-n-play?
 
Update

So I found the manual that came with the conversion kit,

With it i found out that the number 3 button on 2P doesn't have a switch inside, and that the right direction switch of the joystick (also 2P) is non-responsive.

I attempted to find the volume knob according to the manual which placed it somewhere near the middle of the PCB, but it ended up being a flat penny sized black wheel near the edge of it. I adjusted it both ways and used the sound test screen to confirm that there was no sound.

I then followed the wires from the speaker and they appeared to be coming strait out of the Jamma connector with no amplifier for the speaker, I'm guessing that is why i have no sound.

While I was looking around in the cab I found a chip about 2 1/2 inches long and about 3/8's wide I can't remember what the markings were but it was on a sort of riser. There were two very similar chips on the board but with different numbers on them, above them is a opening where the chip i found could be inserted.
