System: Sega Mega-CD
Build date: 1993-05-10
Source: CD-R
Found by: Sega Extreme

Sonic the Hedgehog CD prototype 510, referred to as CD Sonic the Hedgehog on the title screen, is an early prototype of Sonic the Hedgehog CD for the Sega Mega-CD produced on May 10th, 1993. It was 'discovered' by a group of fans called Sega Extreme in the summer of 2000. The original disc has since been sold and is now lost.

The game contains all the stages of the final game, but in a normal playthrough the player can only play the first three: Palmtree Panic, Collision Chaos and Tidal Tempest. The rest can be viewed through the Level Select. This prototype contains several differences from the final game.

-==Differences==
+The game contains all the stages of the final game, but in a normal playthrough the player can only play the first three: [[Palmtree Panic]], [[Collision Chaos]] and [[Tidal Tempest]]. The rest can be viewed through the Level Select. This prototype contains several differences from the final game.
-Differences CD Sonic the Hedgehog 510 were in all respects: Graphics, Music, Zones, Special Stages and the Opening FMV.
-===Graphical Differences===
-*The prototype begins with the display of American Sega CD.
-*SEGA logo appears in 3D while playing SEGA Sound.
-*The Title Screen is very different:
-**Sonic appears in the medal in the shape of her face, and under the medallion, a SEGA's sign golden.
-**In the band with the name, the title ''CD Sonic The Hedgehog'' appears. Also, instead of the sign that indicates the SEGA logo and the year 1993.
-**The clouds are left, the mountains with the face of Dr. Eggman is larger, the menu is top-down and fewer mounts.
-**Also appearing credits toward Keiko Utoku, singer the Japanese and European Opening.
-*In Time Attack screen, the logo of departure brings an image of Little Planet and the chain subject to the mountain of Eggman, instead of the final version.
-*At the end of the panel level, Sonic's face appears with a smile more changed, and the bones of the head are misplaced.
-*In the original game had 3 powers in the video monitors:
-**'''Super Monitor''': Delivery Sonic increased speed and shield of invincibility. It has the symbol of an "S" red.
-**'''Blue Belt''': Meets the same function of the Super Monitor. Has the image of a blue ring.
-**'''Freezer time''': The image of a clock. In tests of the game was not working correctly, but its role was to freeze time for a few seconds.
-*Amy Rose has larger eyes and thorns.
-*Passing the first 3 levels of the game, it closes with a screen that says "COMIN 'SOON'.
-*The lives counter is slightly higher than normal, and there is not there zeros in SCORE and RINGS counters, but leaving the numbers get rings or scoring.
-*The flowers that discards each badnik are different.
-*In Good Future of the zones are badniks.
-===Differences in Music===
+==Comparisons==
-*Tracks 2 to 24 and 32 are equal, but without fadeout.

+==Various Differences==
+{{cleanup|This section needs moving to the comparisons page(s)}}
+===Gameplay===
+*Code is in place for saving data, but only in Time Attack mode at this point.
+*Save data made by this prototype uses the filename "CDSONIC0000" instead of "SONICCD__xx", and is incompatible with later prototypes and the final.
+*Name entry is not yet possible in Time Attack mode.
+*You cannot control your momentum if you jump from a roll, which is normally the case in the Mega Drive games. This was changed in later prototypes and the final.
+*The time warp sequence cannot be skipped by pressing {{start}} yet.
+*Destroying both of the robot teleporters in the Past does not change the future in Act 3 to a Good Future.
+*The game-ending "I'm outta here!" Easter egg does not work properly. The camera will follow Sonic as he jumps off the stage, and he'll die from a bottomless pit, losing a life and restarting the Act instead of causing an instant [[Game Over]].
+*It is possible, using the second controller, to control a second, "virtual Sonic" in gameplay. Whether this is for debugging purposes or an early 2-player prospect is unknown.
+===Audio===
+====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.
+*The Past stages all play the music from the Present, as their own tracks have not been implemented yet.
+*The Invincibility and Speed Shoes monitors do not play their respective music.
+*Pausing the game does not pause the music.
-===Opening FMV Differences===
+====Sounds====
-*The home video is transmitted on a screen in a fund brick. Each brick bears the name inscribed SONIC.
+*Several object sound effects are missing.
-*Also under the screen are Japanese symbols in the text 开発画面, is said in Japanese kaihatsugamen and means ''image development'', between two white edges.
+*The jump sound plays at a lower pitch.
-*There is a scene where there is a takeover of the chain from the ground to Little Planet, the planet that is subject to the chain. In making final scene is put into reverse.
+*The [[Super Peel-Out]] doesn't play any sound effects, but the [[Spin Dash]] does.
-*The video start in beta has a speed of 50Hz.
+*Destroying a badnik plays a different sound rather than the traditional badnik explosion sound.
-*A scene from the mountains of Eggman and the chain shown in the video beta, is not included in the final video.
+*The time warp sound is different, and very grating on the ears. It was changed to a CD audio track in the 712 prototype and then changed to a different sound in the final.
-*The Opening Song hear very badly, with bugs and breaks.
-===Special Stages Differences===
+===Opening FMV===
-Simply, in this prototype, the Special Stage design is not reached 100%, although in the demo of the game, leaving one of them while leaving a text above: "The Programmer Has a nap. Holdout! Programmer!"
+*The home video is transmitted on a screen in a fund brick. Each brick has the name SONIC inscribed on it.
+*A scene from the mountains with Robotnik'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.
-===Zone Differences===
+===Special Stages===
-====Palmtree Panic====
+*The only three special stage backgrounds in this version are Time Stones 2, 3, and 4 from the final game.
-*This is the only level where you can find the 3 special monitors.
+*In a hack by [[User:SegaLoco|SegaLoco]] which enabled controls in this special stage demo, it was found that the oil slick object is non-functioning and that there is no goal in this version of the special stage.[http://forums.sonicretro.org/index.php?showtopic=23875]
+===[[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.)
 *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 as inaccessible.
+*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 tunnel, Sonic is not wound to enter, and could not leave through the other opening. Therefore, Sonic must enter the tunnel at top speed to wrap and leave through the other openings. In a secret tunnel, Sonic walk horizontally to climb.
+*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 future bad 3 of the act, there is a flaw, which comes out if Sonic fired by a spring at the beginning of the level, it gets out of focus of the screen and the same scenario is stuck.
-*The palms of bad future Zone 3 have the same aspect of the palm of good future.
-*The '''EGG-HVC-D01''' prototype of the game in the area has a different aspect. The robot as it is entirely gray, the feet are flat with sharp edges, and have pincers rather than shields rebotadores with a star center. In the final version, the robot has different aspects depending on the type of future in the area. In future bad, rebotadores and parts of the robot are red, while good in the future is lilac.
-====Collision Chaos====
+===[[Collision Chaos]]===
-*The beginnings of the first two zones were different.
+*The beginning of the first two zones are different.
-*In the beginning of the zone 1, leaving Metal Sonic, it is able to electrify Sonic, something that does not happen in the final version.
+*In the beginning of Zone 1, Metal Sonic is able to electrify Sonic.
+*The yellow cups do not function properly yet. They'll catch Sonic, but he won't get sucked inside and will simply freeze there, playing the last animation he was in prior to touching it (jumping or running) until he is freed. The cups won't earn you any points yet, either.
+*The glass bumpers don't have a breaking animation yet and won't award any points for breaking them.
+*A strange group of three spinning teleporter-like objects that don't appear in the final can be placed with Debug Mode. When Sonic jumps into one, he freezes in place and they light up, then he teleports to another object in the group.
-====Tidal Tempest====
+===[[Tidal Tempest]]===
-*The water was different color in all zones, and also altered the graphics.
+*There is no splashing effect when jumping in and out of water.
-*In the prototype had spikeballs appear in fours, this doesn't occur in the final version.
-*In the final game this rush of water is much higher than this prototype.
-====Other Zones====
+===[[Quartz Quadrant]]===
-The other zones can be viewed through the Level Select. This is the highlight of some:
+*All objects use the same sprites across all timezones, appear slightly different from the final, and have incorrect palettes.
+*The conveyor belts were intended to be controlled by standing on buttons, but they don't do anything.
+*Act 2 is devoid of objects in the Past and both Futures, and some of the tubes don't work.
-*In ''Quartz Quadrant'', at the very beginning of Act 1 Good Future, you can view a Sonic The Hedgehog TV, something that doesn't appear in the final. In both version's Bad Future there is an Eggman TV in the same position.
+===[[Wacky Workbench]]===
-*When you begin the Wacky Workbench Zone, you can clearly see that the background has had a different colour scheme to it. In 510, the background is more green coloured, while the final has more of a blue colour.
+*In the Present, the background has a different color scheme. It's more green-colored in this prototype, while the final has more of a blue color.
-*In ''Stardust Speedway'', Zone 1, There is this crazy mixture of colors. That's because the lights of substance which has the stage.
+*The Bad Future's background has a purple color scheme.
-*In ''Stardust Speedway'', Zone 3, Metal Sonic does not appear to make the race.
+*Tubes and tunnels do not work.
-==Cheat Codes==
+===[[Stardust Speedway]]===
-*Level Select: On the title screen, press START in the controller 2 and then hit START in the controller 1. Will come out a black screen with a bunch of numbers and letters similar to selector Sonic CD. Choose the level and press START.
+*Acts 2 and 3 has a slightly higher starting position.
-*Debug Mode: In the middle game, click START on the second controller.
-''Debug Controls'':
+===[[Metallic Madness]]===

+**A trapdoor similar to the ones seen in [[Scrap Brain Zone]] from ''[[Sonic the Hedgehog (16-bit)|Sonic 1]]''.
+*Collapsing platforms have different graphics.
+*The starting positions in Act 3 is much higher up.
+*The conveyor belts and spinning wheels in Act 2 don't work yet.
+*The shrink/growth lasers (placeable with Debug Mode) have a delay before firing each laser. In the final, they are constantly firing.
+*Act 2 is cut off in the "Mini Sonic" maze, as the Goal is at the same coordinates as this area.
+*Act 3 has a different layout.
+*The iron curtain in Act 3 is covering the turntable and spiked wall when it shouldn't.
