List of Sega Genesis games
The Sega Genesis, known as the in regions outside of North America, is a 16-bit video game console that was developed and sold by Sega. First released in Japan in 1988, in North America in 1989 and in PAL regions in 1990, the Genesis is Sega's third console and the successor to the Master System. The system supports a library of more than 700 games created both by Sega and a wide array of third-party publishers and delivered on ROM cartridges. It can also play the complete library of Master System games when the separately sold Power Base Converter is installed. The Sega Genesis also benefited from numerous peripherals, including the Sega CD and Sega 32X, several network services, and multiple first-party and third-party variations of the console that focused on extending its functionality. The console and its games continue to be popular among fans, collectors, video game music fans, and emulation enthusiasts. Licensed third party re-releases of the console are still being produced, and several indie game developers continue to produce games for it. Many games have also been re-released in compilations for newer consoles and offered for download on various digital distribution services, such as Virtual Console, Xbox Live Arcade, PlayStation Network, and Steam.
Sega v. Accolade
As a result of the piracy and unlicensed development issues, Sega incorporated a technical protection mechanism into a new edition of the Genesis released in 1990, referred to as the Genesis III. This new variation of the Genesis included code known as the Trademark Security System (TMSS), which, when a game cartridge was inserted into the console, would check for the presence of the string "SEGA" at a particular point in the memory contained in the cartridge. If and only if the string was present, the console would run the game, and would briefly display the message: "PRODUCED BY OR UNDER LICENSE FROM SEGA ENTERPRISES LTD." This system had a twofold effect: it added extra protection against unlicensed developers and software piracy, and it forced the Sega trademark to display when the game was powered up, making a lawsuit for trademark infringement possible if unlicensed software were to be developed. Accolade learned of this development at the Winter Consumer Electronics Show in January 1991, at which Sega showed the new Genesis III and demonstrated it screening and rejecting an "Ishido" game cartridge. With more games planned for the following year, Accolade successfully identified the TMSS file. They later added this file to the games "HardBall!", "Star Control", "Mike Ditka Power Football", and "Turrican".
