Arrow Lift | Some strange platform. It's not placed in any level, but the graphics fit perfectly in both acts of Launch Base Zone. It has no movement on its own when placed and needs specific PAR codes to be entered to do so. To enable it use the PAR code 1EFC52:1200 and it will replace the first ring monitor. From there enter FFF7E0:00FF to make it move down and FFF7E0:0000 to make it return to it's original position.

8th Special Stage
An 8th Chaos Emerald is accessible via a hidden cheat code. First enter the level select code and then set the sound test selection to 07, and press 
+ 
on the "Special Stage 1" selection to get the 8th special stage from Sonic 3. The Chaos Emerald in this level is yellow, whereas the 8th Chaos emerald was gray in Sonic 3.
This emerald has no special effect in-game, however, and does not appear on the end of special stage tally in any form other than a score increase.
Here's a map of the 8th special stage:
