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 a QSound 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 commonly used in fighting games.

XRGB-2 Specific settings
XRGB-3 Specific settings
As usual with arcade boards, you'll need to set the 220 ohm setting or adjust your potentiometers if your SuperGUN has the controls.
CPS-3 also presents slight distortion on the top 18 lines. To attenuate this, set AFC to manual and AFC level to 3. LPF might also be needed but it commonly isn't. This wokrs on B0 and B1 mode, a reboot of the XRGB-3 might be needed after setting AFC level.
Tested games
Since the platform is basically the same with minor revisions and since a considerable number of games have been tested, it can be safely assumed that they are valid across all boards.
