- You may be looking for the Sega Mega Drive.
The Sega Genesis Controller is a unique Skill that appears in the Xbox 360/Playstation 3 version of Sonic Generations. Usable to both modern and classic Sonic, it enables the player to play the original Sonic the Hedgehog.
The Sega Genesis Controller becomes available in the Skill Shop after completing Green Hill where it can be purchased for 7,777 points. Unlike most other Skills in the series, the Sega Genesis Controller cannot be equipped to Sonic nor does it grant him a new ability. Instead, it unlocks a Sega Genesis in the White Space, on a platform above Green Hill's entrance which the player can play original Sonic the Hedgehog on. After buying the Sega Genesis Controller, the player can also purchase the Infinite Continues which give the player unlimited Continues for that game.
