The Sonic 3D cartridge prototype is a prototype Sega Mega Drive ROM purchased for $700 by the Sonic community and dumped by drx in October 2006. It claims to be a 70 percent complete version of Sonic 3D: Flickies' Island, though it's estimated to be closer to 95 percent. This prototype is very similar to the 819 version, only with some weird values added before the country code.

  • Different "SEGA" sound at the beginning
  • The title screen refers to the E3 demo cartridge, even though it isn't the actual E3 demo.
  • Ending sequences/Chaos Emerald collection screens are missing and have a filler screen instead.
  • Pausing the game then pressing A proceeds to the next level, in the same way the level select does in the final.
  • Collecting 100 rings gives you an 1-UP only if you get exactly 100. Using a 10-rings box to go beyond 100 won't work.
  • Various changes in level design and layout.


  • Various pieces of music are used in in both acts: Rusty Ruin uses Act 1 music, Volcano Valley uses Gene Gadget Act 2 music, Gene Gadget uses Act 1 music, Panic Puppet uses Act 2 music and bosses use the final level music.
  • Two pieces of lost music have been found, one of them was used as a boss track in Sonic the Hedgehog 4 Episode I.


  • Other loading screen / title card fonts
