'''''Sonic the Hedgehog CD prototype 510''''', referred to as ''CD Sonic the Hedgehog'' on the title screen, is among the first prototypes of the game [[Sonic the Hedgehog CD]] for [[Sega CD]]. This prototype was discovered by a group of fans called [[Sega Extreme]] in the summer of 2000. The game contains all the stages of the final game, but at first sight the player can only highlight the first three: ''Palmtree Panic'', ''Collision Chaos'' and ''Tidal Tempest''. The rest can be viewed through the Level Select. This prototype deviates in many ways from what is the final game.

Sonic the Hedgehog CD (Mega-CD prototype; 1993-05-10)
System(s): Sega CD

Genre: 2D Platform

</div>

Sonic the Hedgehog CD prototype 510, referred to as CD Sonic the Hedgehog on the title screen, is among the first prototypes of the game Sonic the Hedgehog CD for Sega CD. This prototype was discovered by a group of fans called Sega Extreme in the summer of 2000. The game contains all the stages of the final game, but in a normal playthrough the player can only see the first three: Palmtree Panic, Collision Chaos and Tidal Tempest. The rest can be viewed through the Level Select. This prototype deviates in many ways from the final game.

Various Differences

Differences between this prototype and the final version span multiple different aspects of the game, including the graphics, music, zones, Special Stages and the Opening FMV.

Graphical

  • A 3D SEGA logo displays while the SEGA sound plays.
  • The Title Screen is very different:
    • 320x224 mode is used, as opposed to 256x224 mode.
    • The SEGA logo is golden.
    • On the ribbon the title CD Sonic The Hedgehog appears.
    • The clouds appear on the left, the mountain with the face of Dr. Eggman is larger, the menu is top-down and there are fewer mountains.
    • Also appearing in the credits is Keiko Utoku, a singer in the Japanese and European Opening.
  • In the Time Attack screen, the exit logo displays an image of the Little Planet and the chain attaching it to the mountain with Eggman's face
  • At the end of a level Sonic looks completely different.
  • The original game had 3 additional power-ups:
    • Super Monitor: Sonic has increased speed and an invincibility shield. It has a red "S" symbol.
    • Blue Belt: Functions identically to the Super Monitor. Has the image of a blue ring.
    • Freeze time: Has the image of a clock. This does not work correctly, but its role was to freeze time for a few seconds.
  • Amy Rose has larger eyes and quills.
  • After completing the first 3 levels, screen that says "COMIN' SOON" is displayed.
  • The lives counter is slightly higher than normal, and there are no zeros in the SCORE and RINGS counter.
  • The flowers that come from each badnik are different.
  • There are badniks in the Good Future of every zone.

Music

  • Tracks 2 to 24 and 32 are the same, but without fadeout.
  • Track 25 and 26: Early version of the title song, very different from the final version. It is a shortened version of Sonic - You Can Do Anything.
  • Track 28: Super Shoes song. A rather strange remix of "Sonic - You Can Do Anything".
  • Track 31: Special Stage song. It is longer than the original. It lasts 4 and a half minutes, and is considerably more "remix" than the original.

Opening FMV

  • The home video is transmitted on a screen in a fund brick. Each brick has the name SONIC inscribed on it.
  • Also under the screen are the Japanese symbols 开発画面. They translate to image development.
  • The showing Little Planet chained to the ground is played in reverse.
  • The video in the beta has a speed of 50Hz.
  • A scene from the mountains with Eggman's face and the attached chain is shown, but is not included in the final version.
  • The Opening Song glitches throughout, with some bugs and breaks during play.

Special Stages

SCD510Programmer.png

The Special Stage design is not 100% completed, although in the demo of the game, one of them is displayed while showing a text at the top that reads: "The programmer has a nap. Hold out! Programmer!"

Zone Differences

Without level select, only the first 3 zones are playable.

Palmtree Panic

  • Amy acts differently than in the final. She will still latch on to you if you run past her, but if you stand still, she also just stands there. (In the final she latches on even if you stop.)
  • This is the only level where you can find the 3 unused monitors.
  • There is a section of a tunnel that appears in the final game, but not in the beta.
  • There is a section of a trunk in a waterfall, which does not appear in the final version, and there's also a section of a tunnel in the final game, which is in prototype but is inaccessible.
  • In the tunnel, Sonic is not wound to enter, and cannot leave through the other opening. Therefore, Sonic must enter the tunnel at top speed to leave through the other opening. In a secret tunnel, Sonic walks horizontally to climb.
  • In the Bad Future of Zone 3, if Sonic is launched by a spring at the beginning of the level, it gets out of focus and the same scenario sticks in the same position.
  • The palm trees of the Bad Future of Zone 3 have the same appearance of the palm trees of the Good Future.
  • The EGG-HVC-D01 in the prototype has a different design. The robot is entirely gray, the feet are flat with sharp edges, and have pincers rather than the shields from the final version. In the Bad Future, parts of the robot are red, while in the Good Future it is lilac.

Collision Chaos

  • The beginning of the first two zones are different.
  • In the beginning of Zone 1, Metal Sonic is able to electrify Sonic.

Tidal Tempest

  • The water is a different color in all zones, the graphics are somewhat different.
  • In the prototype, spike balls appear in fours
  • The waterfall is much lower in this prototype.
  • A ripple effect is added to the foreground. Normally it's only present in the background.

Quartz Quadrant

  • An Extra Life monitor can be found at the very beginning of Act 1 Good Future. This doesn't appear in the final. In both prototype 510's Bad Future and the final version's Bad Future there is an Eggman monitor in the same position.

Wacky Workbench

  • At the beginning of Wacky Workbench, the background has a different color scheme. In 510, the background is more green colored, while the final has more of a blue color.

Stardust Speedway

  • In Zone 1, there is a crazy mixture of colors.
  • In Zone 3, Metal Sonic does not appear to initiate the race.

Cheat Codes

The Level Select screen
  • Level Select: On the title screen, press Start on the second controller and then hit START on the first controller. A black screen with a bunch of numbers and letters similar to selector Sonic CD appears. Choose a level and press Start to select it.
  • Debug Mode: In the middle game, press Start on the second controller.

Debug Controls:

B: Toggle normal and debug mode

A: Advance forward through the debug object list

A + C: Advance backwards through the debug object list
