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.

Unused Graphics
Level Art
| Artwork | Name | Description |
|---|---|---|
 |
Totem Pole | Used in the Master System version, but not here. |
 |
Other Green Hill Tiles | A checkered spike (indicating that spikes may have been placed closer together earlier in development), and an unused corner piece. |
 |
Bridge Zone Tiles | A spring in front of checkerboard, and a pole in front of some sky tiles. The bridges in this zone are never high enough to hit sky level. |
 |
Jungle Zone Spring | A spring not set on grass. Probably intended for Act 2. |
 |
Labyrinth Pillars | Some unused big and small pillar tiles! These were created specifically for the 8-bit versions, and they have no equivalent in the Genesis version. |
 |
Sky Base Tiles | A chain facing southeast, and an unused cannon facing northeast. |
 |
Sky Base 3 Slopes | Just some unused slope tiles. |
Objects
| Artwork | Name | Description |
|---|---|---|
 |
Ground Segment | Appears amongst the object tiles for Bridge Zone. It almost looks like the top is melted. |
 |
Door? | Appears amongst the object tiles for Labyrinth Zone. Perhaps it was intended to be a switch-operated door, like the ones in the Genesis version? |
 |
Shield | This may be a prototype shield animation. |
 |
Unused Enemy | A Bat appears among the Green Hill objects, but isn't used. It was probably meant to be in the caves of Act 2. The Genesis version uses them in Marble Zone, not present in either 8-bit port. |
Ancient
Ancient handled the 8-bit ports of Sonic 1 and were evidently going to credit themselves on the title screen by way of something like "©SEGA/Ancient 1991". In the end, though, only Sega received credit.
