Sonic the Hedgehog (ソニック・ザ・ヘッジホッグ, Sonikku za Hejjihoggu) is a platform video game developed by Ancient and published by Sega for the Master System and Game Gear. The game is not a port of the more popular Sega Genesis version, but is instead an original game released for 8-bit Sega platforms.
Contents

The Master System version was released for the Wii Virtual Console in 2008. The Game Gear version appeared on compilations such as Sonic Adventure DX and Sonic Mega Collection+. A sequel, titled Sonic the Hedgehog 2, was released in 1992. In addition to its original release as a cartridge, the game was later built into some versions of the Master System II in Brazil and Europe.

Gameplay
The game sees players playing as Sonic the Hedgehog as he travels across South Island to steal it from the evil Dr. Ivo Robotnik. Sonic is able to attack enemies by performing a Super Sonic jump Attack, either by jumping into the air or rolling on the ground, the latter of which can also send Sonic off ramps. By collecting rings, Sonic can protect himself from damage from enemies and obstacles. Sonic will lose a life if he is hit without carrying any rings, or if he drowns or falls into a bottomless pit. Items found throughout the game include extra speed, speed shoes, everlasting invincibility, shields and checkpoints. Throughout the game, Sonic travels through six zones, each consisting of two main acts and a boss battle stage. At the end of each main act, the player hits a Goalpost which can award bonuses depending on how many rings Sonic is carrying. If the player has over 50 rings, they can access a bonus stage where more rings and continues can be collected. In each zone, there is a Chaos Emerald hidden somewhere in one of the acts, with a good ending awarded if the player finds all of them and completes the game.
Soundtrack

The game's soundtrack was composed by chiptune musician Yuzo Koshiro. He adapted a few pieces of music from the original 16-bit version by Masato Nakamura, while the rest of the soundtrack consisted of his own original music. "Jungle Zone" was later sampled in the Australian hit single "Accidently Kelly Street" by Frente! in 1992.
Ports and re-releases

A few months after the Master System release, the game was ported to the Game Gear. This version contains some slight changes from the Master System version due to the differences in resolution and color pallette.
The Game Gear version was included as an unlockable game in Sonic Adventure DX, released for the Nintendo Gamecube in 2003 and PC in 2004. The Game Gear version was later included as part of the Sonic Mega Collection Plus compilation, released for PlayStation 2 and Xbox in 2004 and for PC in 2006. The Master System version of the game was released for the Wii's Virtual Console service in August 2008. The Game Gear version then went on to be released for the 3DS eShop in 2014.
