Atomiswave is an arcade system board released by Sammy Corporation in 2003. It was based on Sega's Dreamcast hardware, making it relatively powerful for its time and, later, easier to emulate. Many well-known fighting games and shooters were released for it, including titles from the King of Fighters , Metal Slug , Guilty Gear , and Fist of the North Star series. How Atomiswave Games Run on Emulators Because the Atomiswave is essentially modified Dreamcast hardware, games released for it can be converted to run on a real Dreamcast console or on Dreamcast emulators like Flycast , Redream , or DEmul .
