Cheat codes

  • Level Select code: Up, Down, Down, Down, Down, Up, highlight 1 player, then press A + Start.
  • Debug code: C, C, Up, Down, Down, Down, Down, Up, highlight 1 player, then press A + Start.


  • The title screen is the same as Beta 6.
  • "Sonic and Miles in" appears instead of "Sonic and Miles 'Tails' Prower in".
  • Sound does not stop when the game is paused.
  • Only Up and Down work at the level select.
  • Sound test option at level select is glitchy until highlighted.
  • "Option" instead of "Options".
  • "Sonic only" and "Tails only" instead of xx alone.
  • No Hidden palace, no wood zone, similar to the final.
  • This is the first Sonic 2 prototype since Beta 4 where Debug works.
  • Robotnik's final robot still starts in the center.
  • The laser sound effects that hit Tails' plane are slightly different.
  • Boss music doesn't play during Wing Fortress Zone boss.
  • When Sonic jumps onto the biplane at the end of Wing Fortress Zone, the jump sound plays twice.
  • In the Special Stage, the "(x) rings to go!" message is active; it was not in previous betas. However, even if you have 0 rings to go, the message stays on-screen until the "Cool!"/"Not Enough Rings..." message appears instead of disappearing as in the final.
  • Still contains the Tails megascore glitch.


  • When a level is clear with Super Sonic, Sonic doesn't change back to normal Sonic and the ring counter still drains rings until it hits zero.
