                An 
                  image that shows UFOs in the sky, something that was shown a 
                  fair bit in Sonic 1 promotional things. Also, Sonic's rings 
                  are flying out differently to the complete version. Also it 
                  says "Ring" instead of "Rings" on the HUD, 
                  like most of these images.

                An 
                  odd image of Marble Zone, this image shows that originally there 
                  were flip platforms floating in the air, sort of like Wing Fortress Zone
                  in Sonic 2. The lava is also very different than the final version, as it's more bubble-like, and is glowing from the edges. The ground below Sonic is also a much different shape than the final, with a variety of "floating" platforms.

              A 
                clearer image of the UFOs from Marble Zone. They sort of look 
                like the planet Saturn, and are in a different animation to the 
                top image.

              To 
                the right of the right mechanism, shown by the light coloured 
                bricks, is meant to hold a flame. This version had yet to have 
                it implemented, unlike the picture below.

              This 
                secret area doesn't exist in the game, although there are many 
                others which are found through similar entrys.

              The 
                "Ring" thing is the only thing wrong here, but also 
                notice the fire is on in the background, where it wasn't in a 
                previous picture. This must be a newer version.

                a shot showing the missing "Side Skewer" spikes from 
                marble Zone, seen in the sprites section.

                it's just the "RING" change.
