The CP System (CPシステム shīpī shisutemu?) or CPS-1 is an arcade system board developed by Capcom that ran game software stored on removable ROM cartridges. More than two dozen arcade titles were released for CPS-1, before Capcom shifted game development over to its successor, the CPS-2.
Capcom's Street Fighter II series is perhaps the best known franchise within the CPS game library. The first three titles in the series, the original title, Champion Edition, and Hyper Fighting edition were all developed on CPS-1 and highly successful.
History
After a number of arcade game boards designed to run only one game, Capcom embarked upon a project to produce a system board that could be used to run multiple games, in order to reduce hardware costs and make the system more appealing to arcade operators.
The system was plagued by many bootleg versions of its games. In particular, there were so many bootleg versions of Street Fighter II, that they were more common in some countries than the official version. This problem was virtually eliminated by Capcom in the later CP System II.
The CP System hardware was also utilized in Capcom's unsuccessful attempt at home console market penetration, the CPS Changer (Capcom's answer to the Neo Geo AES).

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 the successor to their previous CP System and Capcom Power System Changer arcade hardware and was succeeded by the CP System III hardware in 1996.
History:
The earlier Capcom system board, the original CP System (or CPS-1), while successful, was very vulnerable to bootleggers making unauthorized copies of the games. In order to rectify the situation, Capcom took the CP System hardware (with QSound) with minimal changes and employed encryption on the program ROMs to prevent software piracy. Due to the encryption, the system was never bootlegged until unencrypted program data became available.
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.
In January 2007, the encryption method was fully reverse-engineered by Andreas Naive and Nicola Salmoria. It has been determined that the encryption employs two four-round Feistel ciphers with a 64-bit key. The algorithm was thereafter implemented in this state for all known CPS-2 games in MAME.

Capcom Play System 3 ( CPS 3 ) Wikipedia information :
The CP System III (CPシステムIII shīpī shisutemu surī?) or CPS-3 is an arcade system board that was first used by Capcom in 1996 with the arcade game Red Earth. It was the second successor to the CP System arcade hardware, following the CP System II. It would be the last proprietary system board Capcom would produce before moving to the more common Taito Type X system boards used in Japan.
History:
The CP System III became the final arcade system board designed by Capcom. It features a security mechanism; games are supplied on a CD, which contains the encrypted game contents, and a security cartridge containing the game BIOS and the SH-2 CPU with integrated decryption logic, with the per-game key stored in battery-backed SRAM. When the CP System III board is first powered on, the contents of the CD are loaded into a bank of SIMMs on the motherboard, where it is executed. The program code is then decrypted at run time via the security cartridge. The security cartridge is sensitive to any sort of tampering, which will result in the decryption key being erased and the cartridge being rendered useless. Games become unplayable when the battery inside the security cartridge dies.
In June 2007, the encryption method was reverse-engineered by Andreas Naive, making emulation possible.
