developers on a freelance basis. Products developed using this strategy include G-Man and Danger Zone by Mike Clark, Terra Cognita by Stephen Curtis, Super Robin Hood and Ghost Hunters by the Oliver Twins, Super Stuntman by Peter Williamson, Lazer Force by Gavin Raeburn, and ATV Simulator by Timothy R. Miller. By April 1987, Codemasters started seeking programmers that would create platform conversions of Codemasters' games in exchange for four-digit sums, via placements in Popular Computing Weekly. 1990s As the 8-bit computer market diminished, Codemasters turned to develop for the 8-bit and 16-bit console markets, as well as moving away from their budget title legacy to more full-price games on the 16-bit computers — 1992 saw the last title in the Dizzy series, Crystal Kingdom Dizzy, released at full-price rather than budget price. They had major success with the Micro Machines series and Pete Sampras Tennis on the Sega Mega Drive. Both franchises featured the J-Cart, allowing two extra controllers to be attached to the game cart without requiring Electronic Arts' 4 way play or SEGA's four-player adaptor. Codemasters is notable for making the large majority of games published by Camerica, which bypassed Nintendo's lock-out chip by glitching it and produced unlicensed NES games. These NES games were known for being shiny gold and silver cartridges. Many Codemasters titles were also featured on Camerica's Aladdin Deck Enhancer. In 1990, Codemasters developed a device called the Game Genie, which came out of the lockout bypass work to play unlicensed games. It was a cheat cartridge for the NES, released in the US by Galoob and in Canada and the UK by Camerica. In the case Galoob v. Nintendo, Game Genie was determined not to violate Nintendo's copyright under fair use. In an effort to establish themselves in the United States, they announced that they would launch a new development studio in Oakhurst, using offices that were abandoned by Sierra On-Line and hiring much of Yosemite Entertainment's laid off staff in mid-September 1999. 1998–2009 Between 1998 and 2003, Codemasters teamed up with Jester Interactive Limited to publish their range of music creation software, for PlayStation, PlayStation 2 and PC, MUSICtm, Music 2000, MTV Music Generator and MTV Music Generator 2. In 2003 this partnership was dissolved, with Jester releasing their own Music 3000 product. Codemasters released their final music based product, MTV Music Generator 3 in 2004. Codemasters have since continued to release
