Locate the SONIC.INI file, and add the following lines to it:
This will add two additional menus, Stage and FUNC, to the menu bar.
A stage select. All Rounds are listed as R1-8, with R2 skipped. Selecting a Round displays a sub-menu for choosing the time zone to go to. Special displays a sub-menu listing all eight Special Stages.
Several menu options are listed here:
- SpriteCmp: Prevents new sprites from loading (which can lead to fatal errors).
- mapinit(): Places the player at the beginning of the current stage.
- DEBUGFLAG: Enables edit mode.
- SPECIALDEBUG: Stops the Special Stage timer.
- TIMEWARP: Disables time travel.
- GO_SPECIAL: Warps the player to the next Special Stage.
- GOODEND: Displays a dialog listing the Time Stones the player has obtained, the Zones where the player has made a Good Future in, and what the next Special Stage is.
- Flags: Displays the following dialog. X will differ depending on the time zone the player is in:
- FRAME: Lists two options, 60 and 30. They don't appear to do anything. Update: In the DINO version this setting works accordingly and allows the game to run at 60 frames per second instead of the default 30. Note that even after selecting 60, the menu will always show 30 as selected, but game will be running at 60fps regardless.
- TIMER (STAT): Appears to do nothing.
- TimerInit (STAT): Appears to do nothing.
- AVE_300Frame (STAT): Appears to do nothing.
- MMTimer: Appears to do nothing.
- SndMemFree: Appears to do nothing.
- RecStart (Demo): Untested.
- RecEnd: Untested.
- RecPlay: Appears to do nothing.
- RecRead: Untested.
- RecWrite: Untested.
- Demo: Displays a sub-menu whose options all correspond to the rolling demos played at the title screen. None of them appear to do anything when clicked on.
- WAVEOPEN: Appears to briefly pause the game before resuming and disables all sound effects.
- WAVECLOSE: Disables all sound effects.
- CDReset: Mutes all music until the game is restarted.
In the OMAKE folder in the disc of the Windows version of Sonic the Hedgehog CD are many BMP files. Most of these are high-quality sprites from the original game and some icons. Below is a collection of them.

|EGG/EGESCAPE.BMP||A sprite of a mechless Eggman running.|
|EGG/EGSTAND.BMP||Eggman making a "Why me" gesture.|

This game contains the most notorious reference to R2, a scrapped level. The level files on the disc skip from R1 to R3 leaving people wondering what R2 was. Eventually, concept art for the scrapped level was released in the Sonic CD developer diary. The extended ending video from Sonic Gems Collection was confirmed to show a brief glimpse of it.
