Sonic the Hedgehog 2 Beta 6 for the Sega Mega Drive was released by drx during the February 23rd, 2008 proto release. It is also known as S2BETA6. There seem to be two versions of Beta 6; but aside from a couple bytes in the header they're identical, byte-for-byte.

General Differences

Cheat Codes

  • Level Select code: Up, Down, Down, Down, Down, Up, highlight 1 player, then press A + Start.
  • Debug code: C, C, C, C, C, C, Up, Down, Down, Down, Down, Up, highlight 1 player, then press A + Start.
  • Level select is still similar to that of Sonic 1 in this build. The level select menu appears behind Sonic and Tails, and Sonic is all black. This is because, as JoseTB explained, "the first line [of the title screen palette] was the background in previous builds, but it's used by sonic in the new title screen. Of course, the level select palette remained untouched with the change."

General Differences

  • The title screen is identical to the final, but the trademark symbol is white instead of yellow.
  • Appears to be the first prototype with the options selection.
  • "Sonic and "Tails" in" (or "Sonic and Miles," depending on region)
  • The special stages remain the same, except with a palette change.
  • As in Sonic the Hedgehog 2 (beta 4) and Sonic the Hedgehog 2 (beta 5), the player can run right past Robotnik in Death Egg.
  • The final boss only takes one hit, most likely to facilitate testing of the newly-programmed full ending. In previous builds, Sonic and Tails just fly off to the right.
  • Super Sonic's ending is not implemented, Sonic's regular ending is used instead.
  • Tails' ending is not implemented; he uses Sonic's.
  • The Sonic 1 style spike behavior has been changed.


  • The "You got a Chaos Emerald!" screen is glitchy.
  • The collision detection in Emerald Hill Zone is a bit wonky in some places.
  • If you complete Wing Fortress Zone as Super Sonic, you'll end up jumping over Tails' plane, and fall to your death.
  • When Super Sonic clears a level he will not go back to normal Sonic and the ring counter will still continue to drain until it hits zero.
  • If Sonic breaks an invincibility monitor and goes Super he will have the invincibility stars. This bug is also in the final.
