The CP System II (CPシステムII shīpī shisutemu tsū?) or CPS-2 is an arcade system board that Capcom first used in 1993 for Super Street Fighter II. It was successor to their previous CP System arcade hardware and was succeeded by the CP System III hardware in 1996. 
The system is comprised of a motherboard (the "A Board") and a game ROM board (the "B Board"). Any game can be used with any motherboard, provided they are region compatible.

The JAMMA+ harness found in CPS-2 boards has 34 pins in two rows. It is multipurpose and the 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 to extend input for three of four player games.
Game regions are identified by case colour, and motherboard regions are identified by a central colour-coded label which also clearly states the region. Quite why there is such a patchy method of region locking globally is unknown.
There are six known types of CPS2 boardsets, which are as follows:
- Blue - USA & European region boards. These are totally interchangeable with the Green Japanese region boards and vice-versa.
- Green - Japanese region boards. See Blue above.
- Grey - Asia region boards. Completely region locked - must have a grey A & B to work.
- Yellow - Region free boards which where intended exclusively for rental. It is thought these where rented out to operators for a limited period so they could "test" their market with a particular game in order to encourage them to buy their own copy.
Yellow boards are particularly notable in that both the motherboards and rom boards are completely region free and as such can be used in combination with any other region's hardware.
- Orange - South American region boards. Completely region locked - must have an orange A & B to work.
- Black - These are rather unique in that they do not have a seperate motherboard, rather they are an all-in-one solution. Only available in Japan; why Capcom decided to offer some games as an all-in-one board remains a mystery althought it is believed only the more popular games are in this format such as Street Fighter Zero 3, Giga Wing and Marvel Vs Capcom, as they made more of them and produced the black all in one boards to reduce costs. These boards have a smaller footprint than the motherboard/rom board combo.

The CP System II consists of two separate parts; the A board, which connects to the JAMMA harness and contains components common between all CP System II games, and the B board, which contains the game itself. The relationship between the A and B board is basically the same as that between a home video game console and cartridge. CP System II A and B boards are color-coded by region, and each board can only be used with its same-colored mate. The exception to this is that the blue and green boards can be used together.
The B boards hold battery-backed memory containing decryption keys needed for the games to run. As time passes, these batteries lose their charge and the games stop functioning, because the CPU cannot execute any code without the decryption keys. This is known to hobbyists as the "suicide battery". It is possible to bypass the original battery and swap it out with a new one in-circuit, but this must be done before the original falls below 2V or the keys will be lost.
Consequently the board would just die anyway, meaning even if used legally it would not play after a finite amount of time (Unless a fee was paid to Capcom to replace it).
Due to the heavy encryption, it was believed for a long time that CP System II emulation was next to impossible. However, in January 2001, the CPS-2 Shock group was able to obtain unencrypted program data by hacking into the hardware, which they distributed as XOR difference tables to produce the unencrypted data from the original ROM images, making emulation possible, as well as restoring cartridges that had been erased because of the suicide system.
The process of reviving a suicided CPS2 game is called Phoenixing. To phoenix a board:
- Purchase the phoenixed EPROMs/data from Razoola
- Reprogram the appropriate program EPROMs with the Phoenix ROM data
- Desolder/Remove the Battery (bottom right corner of the board)
- Short the 2 leads of the electrolytic capacitor next to where the + terminal was together for several seconds. This will drain the juice left in the circuit and allow the phoenix code to operate properly.
Boot up the title. A phoenix logo should appear - at this point, pressing the test button will let the you change the region.
- If a phoenixed board stops working it may be because the electrolytic capacitor next to the + terminal has regained charge. Simply short it out again to revive the board.
A "conversion" is a CPS2 game that has been reprogrammed to a different CPS2 game. Conversions are preformed by reprogramming all of the EPROMs on the B board, and replacing the mask ROMs with EPROMs programmed with data from another title. Depending on the game you want to make, 24 jumpers also have to be set correctly, and the correct PAL has to be used or a wire added.
Conversions are mostly limited to Progear and Hyper Street Fighter II: The Anniversary Edition as these games are relatively expensive. Conversions are easy to identify - the graphics Mask ROMs are replaced with EPROMs (windowed/stickered chips).
