Sonic 2 Cheats (Genesis)

Ashura

To get Ashura, you must enter the level select and debug code. Then you must choose one of the emerald hill zone levels because the code only works in emerald hill zone (1 or 2.) When you start the level press B, you will be a ring,then press a four times,you will be four rings in a row going up or down,you then hold c and right for about 5 seconds,then you go back to the begining, keep pressing a until your the top of a waterfall. You may not see yourself but you're there. Now do the same thing as before, hold c and right for about five seconds. Then press b and you'll be Ashrua, or, green Sonic.

Note 1:The super Sonic Code Will Work If You Get 50 rings or more and jump into the air to change

Unlimited 2 player vs. lives

To do this code, go to 2 player vs. and select Mystic Cave. Go and die on the spikes and a "Y" will appear next to your lives. Keep on hitting the spikes. There will be an -> next to your lives and you will have 9 lives. Now you can beat the other player because you can die and various signs appear!
