An early prototype of Sonic the Hedgehog CD for the Sega CD.
- This prototype was featured at the Yuusei Sega World (遊星セガワールド) event in 1992. The event was available to the public and was also the first public appearance of Sonic the Hedgehog CD worldwide.
- This prototype was built almost a full year before the final retail release and seems to have been built specifically for the event, as it only contains files for just the playable content (with a few exceptions).
- The prototype was also used as an early preview for various magazines in the months following the event.
- General Differences
- The name of the disc volume itself is named after the game "Dark Wizard" which came out around the time Sonic CD was being made.
- The disc header specifies that the title of the game is "CD SONIC THE HEDGEHOG" rather than "SONIC THE HEDGEHOG CD". The header also lacks a proper game code and with a date of APR 1993 (which might be the original projected release date, as many magazines at the time predicted the game would be out sometime within 1st/2nd quarter 1993).
- The game boots to a SEGA logo complete with SEGA scream. This would be featured in later prototypes but would eventually be dropped.
- The title screen is different in comparison to the final version, but is similar to the one featured in later prototypes. The only difference between this build and later prototypes is that the chosen song is the full "You Can Do Anything" instead of a short arrangement. The version of "You Can Do Anything" uses a different vocal take and is the same version featured in Sonic Jam and various albums (True Blue, the 10th Anniversary album, etc).
- The title screen doesn't contain code for the level select cheat, so it's impossible to load the menu without hacking.
- The opening video contains more artifacts than can be found in the final version. "You Can Do Anything" doesn't play during the opening video. The frame is also different, containing a message that says "開発画面" (which translates to "Development Screen").
- Only the opening video can be seen after the title screen. There are no gameplay demos.
- The Time Attack menu is completely different in comparison to what would be used in later builds. At this point, the game still has eight zones rather than seven. The name of the first zone is called "Salad Plain" instead of "Palmtree Panic". No other graphics exist in the game for the other zones, hinting that this menu was put together rather quickly for the demo. The menu itself also uses Collision Chaos Present's BGM instead of D.A. Garden.
- Gameplay Differences
- There are no title cards when starting a stage.
- If you press start on the second controller, you can spawn a second "ghost" Sonic just like later builds that have a debug mode. However, it's impossible to activate the debug mode in this build without hacking since the check for the debug mode flag was removed from Sonic's object code.
- Sonic's ledge animation is the same as the one from Sonic 1.
- Sonic lacks the Super Peel Out animation he has in later builds. This build uses his normal run animation instead. It's also not as fast as it will be in later builds.
- The camera doesn't move forward while running.
- Sonic's spindash is too fast if held for a long time.
- Sonic's animation after waiting three minutes is much different in comparison to what's used in later builds. Sonic doesn't say "I'm outta here!" when he jumps.
- The game can't be paused.
- The sign post at the end of each act says "You Say!" instead of the usual sign post. This is a play on words on the name of the event that this prototype was featured in. When you pass the sign, Sonic automatically moves right and the stage ends automatically, there is no score tally screen or Level Complete BGM.
- There are no checkpoints in any of the stages.
- Sonic can travel to the past and future, but there's no way to create a good future in this build. However, the files for the good future versions of the stage exist in this build but go unused.
- The time travel screen is different and uses the invincibility stars from Sonic 1.
- When Sonic appears in a new time period you'll lose any rings you collected. This can sometimes lead to a scenario where you might land on top of a badnik and die instantly upon entering.
- If you finish the second act or lose all your lives, the game ends and goes to a "COMING SOON" screen. Unlike later builds, this build uses the Good Future BGM for Palmtree Panic instead of the Invincibilty theme.
- The Past uses a unique Redbook audio track instead of a PCM track. This version was never released on any soundtrack before.
- All Redbook audio tracks lack a fade out except for the track used for Salad Plains Past.
