Lost Sprites

Artwork	Name	Description
	Totem Pole	Not really lost in the Master System game as it is used there, but it is unused in the Game Gear version, yet the graphics still exist there.
	Round thingy	This may be a prototype shield animation.
	Unused Enemy sprites	KT15 found unused sprites in Green Hill Zone. These two animations are unused, however, another animation is used, but it is used in Jungle Zone, not Green Hill. This sprite is only found in the Master System version of the game.
	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 thierselves on the title screen as can be seen from this VRAM window. However, they left this out totally and in the end only Sega recieved the credit on the Title Screen. If it were used it probably would have appeared on the bottom of the screen reading Sega/Ancient 1991.
