The CP System II (CPS-2) is the arcade board that Capcom introduced in 1993 with Super Street Fighter II as the successor to its CP System. It kept most of the earlier architecture, added QSound audio and encrypted the program ROMs as a defense against the bootlegging that had affected CPS-1.

THE STORY
About the CPS-2
Each installation joins an A board, which holds the components shared by every game and connects to the JAMMA harness, with a B board that carries the game; both sit in plastic cases color-coded by region. Decryption keys are held in battery-backed memory, so a board stops working once its battery runs down, a mechanism known as the 'suicide battery'. Hobbyists obtained decrypted program data in 2001, which made emulation possible, and the encryption scheme was fully reverse-engineered in 2007.
Although the CP System III arrived in 1996, new CPS-2 games kept appearing until Hyper Street Fighter II in 2003. Capcom stopped manufacturing the hardware on December 22, 2003 and ended all official support, including battery replacement, on February 28, 2019.
- Program ROMs are encrypted with two four-round Feistel ciphers and a 64-bit key.
- Up to 900 sprites on screen and 4,096 colors from a 16.7-million-color palette.
- Maximum ROM capacity of 322 Mbit (40.25 MB).
- QSound positional audio was used in all CP System Dash and CP System II titles.
- New releases continued until Hyper Street Fighter II (2003), outliving the CPS-3 by over four years.
