Sonic the Hedgehog (Game Gear)

The Game Gear version of Sonic the Hedgehog appears to have been a port of the Master System game, as it was not only released two months later but removes some unused sprites while adding others. The smaller screen also meant that things had to be scaled down, resulting in the Green Hill boss being laughably easy.

Ancient


Ancient handled the 8-bit ports of Sonic 1 and were evidently going to credit themselves on the title screen with the text "©SEGA/Ancient 1991". In the end, though, only Sega received credit.
