Nine Bonus Stages (six Sonic 1 Special Stages as Bonus Stage) which can be accessed by touching a lamppost with 20 or more rings. The formula for selecting which Bonus Stage will be played is “RING” count divided by 4 and the remmainder of operation will give the stage to be played:

0 – Slot Machine;
1 – Glowing Spheres;
2 – Gumball Machine;
3 – Sonic 1 Special Stage.:

You can play as:

Sonic and Miles;
Sonic Alone;
Miles Alone;
Knuckles and Miles;
Knuckles Alone.

All Characteres have Super and Hyper Forms. For Miles the Super Form has no flickies. In Sonic 1 and Sonic 2 part you will play Sonic 2 Special Stages through big ring (50 rings or more is required ) at end of levels. After Knuckles steal your emeralds in Angel Island you need to get all Emeralds again, now through S3 Special Stages.

Extra:

Debug object list works for all levels;
Demo mode edited to show some Sonic 1 and Sonic 2 Levels.

Hints:

If you are running debug mode to test, when Sonic is an object, hold “A” then press “C” to backwards the objects list. You can select the Egg Prison to skip that level.
The Perfect Bonus in the Sonic 2 Special Stage is given if you do not hit any bombs and complete the stage (You must protect Miles too in the cooperative mode).
If you use Save State in emulators for Sonic 1 and Sonic 2 levels probably the game will crash after the Save State is loaded. This occur because emulators does not save the SEGA Mapper state. To get the Save State working just start a New “No SAVE GAME” and after the Green Hill is loaded you can load the Save Sate.
