Known Differences

This short section needs expansion. You can help Sonic Retro by adding to it.
  • There is no Sega Logo in the beginning.
  • Sonic is placed further right at level startup.
  • Sonic's palette changes to a darker blue when passing the end level sign.
  • A strange strip appears at the top of the level briefly, probably a glitch as touching it does nothing.
  • There are 2 invincibility stars in the prototype. The final Game Gear version has 4 stars.
  • Sonic's sprites are exactly close to the ones from the Master System version.
  • The map layout is slightly different than any version.
  • The "GAME OVER" screen is garbled.
  • The mountain range has a different hue, which resembles more to the hue from the Master System version.
