CPS-III
Capcom System III is an arcade platform developed and used by Capcom. It consists of one board with flash-SIMMs and a CD-ROM drive, with the games using a special cartridge and a CD. It is a JAMMA system with a JAMMA+ harness and stereo RCA connectors for use with an external amplifier.

Harness
The JAMMA+ harness found in CPS-3 is 32 pins in two rows. It is most commonly used as a Kick harness, extending the JAMMA 3 buttons per player to 6 buttons, and is used by all the games in this platform.

Suicide
XRGB-2 Specific settings
As usual with arcade boards, you'll need to set the frontal switch to PCB or adjust the potentiometers if available in the SuperGUN.
There are no problems with the signal.
XRGB-3 Specific settings
As usual with arcade boards, you'll need to adjust the 220 ohm setting or use the potentiometers if available in the SuperGUN.
CPS-3 also presents slight distortion on the top 18 lines. To attenuate this set AFC to manual and AFC level to 3, it only reduces the problem in B1 and eliminates it in B0. A reboot of the XRGB-3 might be needed after setting AFC level.
Tested games
Since the platform had just very minor revisions and half of the existing games have been tested, it can be safely assumed that they are valid across all boards.
