Capcom Play System II (CPS-2)

The CP System II (CPシステムII, CP shisutemu 2), also known as Capcom Play System 2 or CPS-2 for short, is an arcade system board that was the successor to Capcom's CP System, CP System Dash and Capcom Power System Changer arcade hardware. It was first used in 1993 for Super Street Fighter II and was succeeded by the CP System III hardware in 1996, of which the CPS-2 would outlive by over four years. New releases for the system were produced until the end of 2003, ending with Hyper Street Fighter II. Technical support for the CPS-2 ended on February 28, 2019. Like its predecessor, games can be exchanged without altering the core hardware. The CP System II uses separate daughterboards enclosed in plastic cases to store both the games and the main board on, which are then put together so that the games can be played. Unlike its predecessor, however, games are encrypted, and must be decrypted via a decryption key stored on the main board's battery-backed memory to run them.
