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.
Bored ending:
Allow Sonic to sit for three minutes without doing anything. He will grow bored, say "I'm outta 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.

PSA: we do not support cheating for online/mobile/multiplayer games, which may include trainers,
mod menu's, Exploits, Hacks, Tools & Macros, Bots and so on. (we do allow the posting of such for offline/single player games hoewever, online and multiplayer games is where we draw the line. Phone apps/games for example typically offer a storefront to purchase ingame currency for example; whether it's singleplayer or not, in such games, the aforementioned is not allowed.)
