Debug mode: Enable the "Sound test mode" code. Set the
options to PM12 and DA11. If done correctly you
should see a picture of Tails, and a sign that says "See
you next game". Hold B and choose "Play Game".
To change into a object, press A. To turn into your normal
self, press A again. Note: If you try to do this in time
attack mode, you will go through objects, meaning you cannot jump
on anything (springs, robots, spikes). Also, in a original game
you cannot put down a object that you turn into.

Enable the "Sound test mode" code. Set the options to
FM40, PCM12, DA11 and press Start.
A screen with Tails will appear. Begin game play, and press B
to change into an object, A to select another object, or
C to place the object on the screen. While debug mode is
enabled, the completion time for each level will be "0:00".
Bored ending: Allow Sonic to sit for three minutes without doing
anything. He will grow bored, say "I'm outa here!" and
race off the screen, thus ending the game.

Play your own music: You can play your own audio CDs while you play the
game. To do this, pause game play and eject the game disc from
the Sega CD tray. Replace the game disc with an audio CD. When
you close the cover, wait about four seconds for the console to
start the CD spinning. When you resume the game, you will hear
the music from the audio CD. If you complete a zone or lose all
of your lives, re-insert the game disc and it will pick up where
it left off. You can also use this trick with CD-Rs.
