System(s): Sega Mega Drive
Publisher: Sega
Developer: Sonic Team
ROM size: 4 MB
Genre: Action

Sonic the Hedgehog 3C Prototype 0408 is a prototype for the canceled Sonic the Hedgehog 3 and Sonic & Knuckles compilation called Sonic the Hedgehog 3 Limited Edition for the Sega Mega Drive. It claims to have been built on April 8th, 1994 at 17:29.

This prototype was released by drx during the February 23rd, 2008 proto release. A later in development beta with a compilation number of 0517 was also found. When this beta was obtained by drx the file was labeled "3C" indicating this was a unreleased version of Sonic 3. Due to the late development date (dating after Sonic 3's release), it's obvious this isn't Sonic 3 before it was split into 2 games.

• The ending sequences have yet to be implemented.

Audio Differences

• The music for the title screen, mini-bosses, Knuckles, invincibility, and collecting 1-ups are all from Sonic 3.
• Many sound effects are missing, especially in the Sonic & Knuckles Zones and when playing as Knuckles.
• Has additional unused sound bytes of music at the following sound test codes: 24, 23, 32, 2D, 22, 21, 20, 1E.
• Sound test numbering is different for most sounds. Lots of empty slots for sounds in the sound tester.
• The Data Select music bug from Sonic 3 alone is still there.
• If Lava Reef act 4 (Hidden Palace Zone) is accessed via Level Select it will use Sky Sanctuary music.
• The lead echo track of Flying Battery Zone's Act 1 music will go off sync after the first loop, and will increasingly gain drag behind after every loop.

Angel Island Zone

• Act 1 will still play Act 2 music when returning from a Bonus Stage after the Zone has been set on fire, like in Sonic 3.
• Knuckles' route in Act 2 still has its object layouts from Sonic 3.

Carnival Night Zone

• When playing as Sonic alone in Act 1, Tails randomly appears after the boss. (This randomly happens in the completed Sonic 3, but with a different frequency.)

Bonus Stages

Slot Machine

• There is a higher chance of getting 3 Robotnik/Eggman pictures on the slots than in the final version.
• Using debug to fall out of the stage causes the game to crash. In the final, it takes you to a glitchy area with randomly placed tiles, a la Sonic 1.
