Hidden ImagesEdit


FM40 PCM12 DA11 A picture of Tails next to a Lotus 7 , with the text reading "SEE YOU NEXT GAME". This picture foreshadowed the upcoming Sonic Drift. This code also enables Debug mode.


FM44 PCM11 DA09 A drawing of Sonic with big, grey eyes with Japanese text above him. The text reads: "ゆーあーくーる", which can be translated as "You are cool" in English.


FM42 PCM04 DA21 A bizarre tribute to Batman.


FM42 PCM03 DA01 A DJ scene with Sonic, Metal Sonic, and Dr. Robotnik.


FM46 PCM12 DA25 A screen of disturbing looking Sonics and Japanese text which reads: "Infinite Fun. Sega Enterprises. -Madzin".

Apparently this is a message from Masato Nishimura, one of the landscape designers of Sonic CD. "Madzin"(which is pronounced the same as "majin") was Masato Nishimura's nickname since he was a child, "majin" being an alternate way to read his given name. also weird music plays in the background

In the 2011 remake of Sonic CD, a sixth image can be accessed:


PCM32 DA08 An image of Desert Dazzle, a zone Christian Whitehead wanted to put into the remake of the game, but it was cancelled and removed from the final game. This code also enables the player to choose Tails in the stage select menu. Desert Dazzle would finally see the light of day in Sonic Mania as Mirage Saloon Zone.

Hidden Special StageEdit


A hidden special stage can be accessed:

FM07 PCM07 DA07

"I'm outta here!"Edit

Leaving the controller alone will eventually cause Sonic to look at the you with an annoyed look on his face. After the controller is left alone for 3 minutes, Sonic will say "I'm outta here!" & jump off the screen, effectively giving you an instant game over, regardless of how many lives you have.

Invisible ShieldEdit

While not necessarily an easter egg, if Sonic has a shield equipped, and if one takes a screenshot, the shield won't show visible.
