Knights of the Round (video game) in the context of "CP System"

The CP System (CPシステム, CP shisutemu), also known as Capcom Play System or CPS for short (and retroactively as CPS-1), is an arcade system board developed by Capcom that ran game software stored on removable daughterboards. More than two dozen arcade titles were released for CPS-1, before Capcom shifted game development over to its successor, the CP System II. Technical support for the CPS-1 ended on March 31, 2015.

The CP System is best known for its many beat 'em up titles such as Dynasty Wars, Final Fight, The King of Dragons, Captain Commando, Knights of the Round, Warriors of Fate, Cadillacs and Dinosaurs, and The Punisher, as well as fighting games such as Street Fighter II and Muscle Bomber.
