Gens is a free Sega Genesis emulator. It runs on Windows systems (using DirectX), on Linux (using SDL) and on Microsoft's Xbox. A port to the Sega Dreamcast, known as Gens4All, is currently in development. Development of Gens began in 1999. As of July 2006, the current version (2.14) advertises full compatibility with 92% of all Genesis games and is considered to be one of the most compatible Genesis emulators available, although its Yamaha YM2612 emulation is far from perfect.
