Glitch: Becoming Super Sonic in Emerald Hill - an alternate way
For all those who like to play honest instead of cheating all those Chaos Emeralds together, there's an alternate - yet simple - way to become Super Sonic in Emerald Hill Zone 1. It involves some serious work, however:
1. Complete the special stages as you would usually do and collect as many emeralds as you want.
2. Press [Reset].
3. Start a new game USING THE OPTIONS MENU! This is crucial! Otherwise your emeralds are gone for good!
4. Continue collecting the emeralds, if you don't have them all, yet and repeat point two and three until you got them all.
If you did everything correctly, after your last reset you should have all the emeralds from the very beginning and without using any code ever thus making Super Sonic available from the very beginning.
This has been tested and confirmed with the PAL version of Sonic 2 playing on a PAL Megadrive II.
Oil Ocean Music for Ever
Simple really... go to the sound test in the option menu and put in the sounds, 2, 1, 2, 4, and hold [A] and press [start]. The oil ocean music will now be playing constantly, no matter what stage. Note: no sound effects can be heard only the music.
Pseudo Super Sonic
In Oil Ocean Zone, if you manage to take a hit and end up landing in one of those green-and-gold checkered cannons, you'll fall right out, but you'll be moving at twice your normal speed as well as jumping twice your normal height(with twice as much gravity). A good place for doing this would be in Oil Ocean Zone, Act 2, near the first set of pop-tops and cannons. Just jump into the semi-hidden bed of spikes on the right and land in the cannon. Note: Moving at twice normal velocity can often get you stuck in a wall. Also, this wears off if you Super Spin Dash or Spin Dash. It also only lasts for that Act.
Unlimited speed shoes in 2 Player VS mode
In 2 player VS mode, get speed shoes and die (while you still have them) and you will get to keep your sped shoes 'til the end of the level.
