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.
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).
