Standard is 2 joys 3 buttons per player.  More buttons require a kick harness.

It's just an extra wiring loom that has the connectors on it for the extra buttons. Also known as Jamma+ (And these looms are not standardized, pinouts can vary between PCB's).

I thought Jamma supports 1 joystick and upto 4 buttons per player.

And before you ask, a J-pac has additional screw terminals for buttons 4-8.  ;D

The 4th button pinouts are there to be used tho on the wiring loom.

Button 4 can be on the jamma connector but in the most commonly used pin out P1/2 button 4 are labeled as not used and the kick harness is used.  An example of this is MK I which uses buttons 123 on the jamma but 4 and 5 are on the kick harness.

Yeah, what BobA said (both times!) ... Button 4 is simply not part of the JAMMA standard, although some games do use the unused pins on the connector for Button 4. If you are looking at a "JAMMA game" with more than 2 players or 3 buttons, you need to look at the pinouts.

Cheers.

Ahh cool, my cab didn't come with a PCB all I knew it was wired for 4 buttons via the Jamma connector.
