From the main screen, select Options. Select "Sound Select" and play sounds
19, 65, 9, 17, then push C. Press Start to get back to the main screen.
When Sonic and Tails appear, hold Down A and press Start. This will let
you choose the level in which you begin your game. When playing, you can
pause the game and use A to restart, B for slow motion, and C for
frame advance.
To become Super Sonic without getting all the Chaos Emeralds, first enable
the level select. At the level select menu, go to the sound test item, and
play sounds in this order: 4, 1, 2, 6. You should hear the music you get
when you win a chaos emerald. Now select any level, get 50 rings, and jump.
First enable the level select. Then, at the options screen, play these sounds
in this order: 1, 1, 2, 4. Now move the highlight to the "Player Select" field
of the options screen and press Start.
To enter debug mode, play these sounds from the level select screen: 1, 9,
9, 2, 1, 1, 2, 4. Press Start and hold A. The controls work as they do in Sonic.
Start the game as you normally would. Get a chaos emerald, reset the game,
and Start the game from the options menu. You will keep the emeralds you
have gained so far each time you Start from the options menu.
While in DEBUG mode, pick the monitor. It should be a transfer box. When
you hit it and you are Super Sonic, you lose all your powers but stay yellow.
Tails looks the same but has invincibility (little stars flashing around him).
