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.
