Hidden Images[]


FM40 PCM12 DA11

"See you next game!" -Judy Totoya

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.


"You are cool."

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. Adorable. A Lot. And It’s True. You Are Cool.


"Inevitable BatSonic."

FM42 PCM04 DA21 A bizarre tribute to Batman. Just look at that face.


Metal Sonic: "The Fastest DJ, Mc Sonic", Dr. Robotnik: "Can I kick it?", Box: "Come in Bad boys!" -Made by K.H.

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


FM46 PCM12 DA25 A screen with disturbing looking Sonics and Japanese text which reads: "Fun is Infinite. 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. But "Majin" is also a Japanese nickname for Devil which is why it was considered scary. It doesn't help that the boss music plays during this as well, making this image creepier in the American version. But the Japanese and European versions is more silly. Since Sonic CD is designed with the Japanese soundtrack, this image is probably supposed to be funny. But why is this so creepy if the text is just "infinite fun"? Because most kids in America can't read.

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. Elements of this level were incorporated in Sonic Mania’s Mirage Saloon. The original "R2" was going to be Rainbow/Relic Ruins however it ended up being cut and only a sketch and some enemy designs are leftover from development.

Hidden Special Stage[]



A hidden special stage can be accessed: The stage has a giant Dr.Robotnik in the background

Instant Game Over[]

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. However, This does not happen with Tails.
