This is the first Sonic game in the series to be released for the SEGA Master System and, shortly afterwards, the Game Gear. The game was later built-in to some editions of the Master System II.
In 2008 the game was ported for the Nintendo Wii Virtual Console, it was also announced in 2013 that the game would be made available for download for the 3DS The game was also included in the following compilations or as an unlockable bonus:
- Sonic Adventure DX for Nintendo Gamecube and PC.
- Sonic Mega Collection Plus for Nintendo Gamecube, Sony Playstation 2 and Microsoft Xbox.
The game is much like the 16-Bit edition of Sonic the Hedgehog with the same game mechanics. Rather than each zone containing 3 acts, in this edition there are only 2 plus a boss at the end. Additionally there is a Special Zone but, unlike the Mega Drive version, there is no Chaos Emerald to collect, it is purely for collecting rings and extra lives. The Chaos Emeralds are hidden in one of the first two acts of each zone.
