1985 in the United States. Karate Champ was the first successful fighting game, and one of the most influential to modern fighting game standards. Some of Data East's other most famous coin-op arcade games from its 1980s heyday include Heavy Barrel, Bad Dudes Vs. Dragon Ninja, Sly Spy, RoboCop, Bump 'n' Jump, Trio The Punch – Never Forget Me..., Karnov and Atomic Runner Chelnov. Data East also purchased licenses to manufacture and sell arcade games created by other companies. Some of its licensed games included Kid Niki: Radical Ninja, Kung Fu Master and Vigilante, all licensed from Irem, and Commando, licensed from Capcom. It had a brief stint as a Neo Geo arcade licensee in the mid-1990s, starting with Spinmaster and co-published with SNK. Following its arcade success, Data East made a successful entry in the home computer game market with a 1985 port of Karate Champ, which became the first home computer game to sell more than 500,000 copies in the United States by January 1989. It became the subject of the litigation Data East USA, Inc. v. Epyx, Inc., in which Data East alleged that the computer game International Karate (1985), published by Epyx, infringed the copyright of Karate Champ. Data East entered the video game console market in 1986 with the release of B-Wings for the Famicom. In North America, the subsidiary Data East USA was the first third-party company to release video games for the NES. Data East would become a licensee for several home systems, notably the NES (1986), PC Engine (1988), Game Boy (1990), Mega Drive (1991), Super NES (1991), Neo Geo (1993), Sega Saturn (1995), PlayStation (1996), WonderSwan (1999) and NeoGeo Pocket Color (1999). Several of Data East's video games series, such as Tantei Jingūji Saburō, Glory of Hercules and Metal Max, were created specifically for home consoles. Data East also made pinball machines from 1987 through 1994, and included innovations such as the first pinball to have stereo sound (Laser War), the first usage of a small dot matrix display in Checkpoint along with the first usage of a big DMD (192x64) in Maverick. In designing pinball machines they showed a strong preference for using high-profile (but expensive) licensed properties, rather than creating totally original machines, which did not help the financial difficulties the company began experiencing from 1990 on.
