Unused Graphics
Level Art
| Artwork | Name | Description |
|---|---|---|
 |
Totem Pole | Not really lost in the Master System game as it is used, there, but while the graphics still exist in the Game Gear version, it isn't used. |
 |
Other Green Hill Tiles | Another 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 Sonic the Hedgehog. |
 |
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 | This appears amongst the object tiles for Bridge Zone, in both the Game Gear and Master System versions. It almost looks like the top is melted. |
 |
Door (?) | This appears amongst the object tiles for Labyrinth Zone, in both the Game Gear and Master System versions. 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 | This Bat sprite appears in Green Hill Zone, but isn't used. It was probably meant to be in the caves of Act 2. In the 16-bit version, this is a normal enemy in Marble Zone, a level not found in this version. This sprite is only found in the Game Gear version of the game. |
Ancient
Ancient handled the 8-bit port of Sonic the Hedgehog, and it looks like they intended to credit themselves on the title screen, as can be seen from this VRAM window. However, in the end only Sega received the credit on the Title Screen. If it were used, the copyright text likely would have read, "©SEGA/Ancient 1991".
