Sonic the Hedgehog 2 for Master System was released on October 16, 1992 in Europe. It was then released in Brazil by Tec Toy the following year. It didn't appear in Japan or North America until the Virtual Console release on the Nintendo Wii years later (See Ports below).
The Master System version is totally different than the Sonic 2 for Mega Drive. Tails obviously doesn't accompany you, like he can in the Mega Drive release. Sonic can also not do his infamous buzz saw roll by simply ducking and pressing jump.
