Some cheats of the original game are now unlocked through getting a certain total in Time Attack or its Special Stages section, the latter of which unlocks after completing the former's total within 30 minutes.
D. A. Garden
To unlock D. A. Garden, the player must complete within 30 minutes for the combined Time Attack score, or collect all 7 Time Stones.
To unlock Visual Mode, the player must complete within 26 minutes for the combined Time Attack score.
To unlock Sound Test, the player must complete within 4 minutes for the combined Special Stages score in Time Attack.
To unlock Stage Select, the player must complete within 5 minutes for the combined Special Stages score in Time Attack. It will actually carry over the selected character and Time Stone progress from the save file most recently used before accessing it.
To unlock Tails, you must beat the game once.
"I'm outer here!!!!"
Wait 3 minutes without doing anything, and Sonic will say, "I'm outer here!" [sic] and jump off the stage, ending the game.
Sonic's line is commonly heard as "I'm outta here!", though designer Masato Nishimura, who also provided the voice clips for Sonic in the game, stated on Twitter in July 2017 that the intended spelling for the line is "I'm outer here!".
Play 8th Special Stage
In the Sound Test, set the values to PCM07, DA07. This will access an 8th Special Stage with Robotnik's head in the background.
Alternatively, within the Special Stages section of Time Attack, select one of the Special Stages then immediately exit with the back button. This will show the 8th Special Stage's Time Attack screen and allow you to play it there like any other Special Stage. But despite this, time scores made here will not be retained by the game.
Beating this hidden Special Stage normally will display the remaster's credits, also seen when beating the game with Tails.
Tails' message and edit mode
This will also enable edit mode.
In the Sound Test, set the values to PCM12, DA25. The message says たのしさ∞ セガ・エンタープライゼス まぢん画 (Infinite fun. Sega Enterprises - Mazin Picture), and was made by Masato Nishimura. The boss theme plays on this image.
In the Sound Test, set the values to PCM04, DA21. The image was made by Takumi Miyake, and Final Fever plays on this image.
Dessert Dazzle and Stage Select
In the Sound Test, set the values to PCM32, DA08. This will showcase the scrapped remaster Zone of Dessert Dazzle. This will also enable the Stage Select to be played exclusively with Tails, with the Time Stone progress from the most recently accessed save file still being retained.
These are various graphics that are unused in the final game.
|This was to be placed next to the also unused "D-Pad" menu selection item. Likely a cut feature from the Android and iOS versions to enable touch control features.|
|A sprite of a stopped sheep is found within the files for Metallic Madness. It was used for the Metal Sonic Projector, if it were ever place within the Past of the first two acts. Since Metal was destroyed in the previous Zone, it was left unused.|
|This text was found in an early Stage Select. Meant for a scrapped final level. For more info about Final Fever, see the Final Fever wiki page.|
|This was found next to Sonic's sprite for the character select screen. This sprite is displayed on non-Japanese Mega-CD systems when loading a game.|
|Sprites of Tails hanging upside-down. Sonic has similar upside-down sprites in the Mega-CD version.|
|May be related to Retro SDK's level editor which was used to develop the game.|
|A Time Attack icon placeholder.|
|The exit icon on the Mega-CD and Windows 1996 versions of the game. This represents the 8th Special Stage in its hidden location within the Time Attack.|
