Capcom System II is an arcade platform developed and used by Capcom. It consists of two boards, named A and B. The A board is the base of the system, and contains the CPU, DSPs, JAMMA connector, a JAMMA + harness and stereo RCA connectors for use with a QSound amplifier. The B board goes on top using four connectors and holds all the game data.

Compatibility

There are two kind of conenctors in teh boards, these make the games physically incompatible between certrain regions. The boarda are colores to reflect their region, and thus their compatibility in general terms. However, there are boards that have been officially adapted for a different region than the one identified by the color.

Regions are:

Color Region Compatible with
Blue USA Japan
Green Japan USA
Yellow Japan (Rental Only) USA
Orange Hispanic Asia
Gray Asia Hispanic

There are also black metal boards, which are a complete system and thus, they have no A and B parts.

Harness

The JAMMA + harness found in CPS-2 boards is 32 pins and two rows. It is multipurpose and teh game might use it for different input options. 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.

It can also be used for and 3rd and even 4th player, Alien Vs. Predator and the Dungeons & Dragons games use the port for this purpose.

The volume up and down buttons in the harness have the same effect as the ones in the board.

The harness is compatible with the Sega Naomi I/O board by Capcom and CPS-3 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-2 also presents slight distortion on the top 18 lines. To fix this set AFC to manual and AFC level to 3. LPF might also be needed but it commonly isn't.

Here are pictures detailing the distortion on teh top lines before and after adjusting AFC level.
