The NeoGeo CD is the second home video game console of SNK Corporation's NeoGeo family, released on September 9, 1994, four years after its cartridge-based equivalent. The system can also play Audio CDs. All three versions of the system have no region-lock. The NeoGeo CD was launched bundled with a control pad instead of a joystick-like AES version. However, the original AES joystick can be used with all three NeoGeo CD models.
