General Differences

  • No copyright and date screen.
  • You can skip Options if not on the title page.
  • The music is at a lower pitch and has slightly different instruments than the final
  • The message says Let's go next floor! instead of Let's play a game!
  • Robotnik is mis-spelt as Robotnick throughout the game.
  • The message says Have you played Sonic's Toy Grab? instead of The Toy Drop is fun!
  • The casino floor from the Japanese version is still there but glitched with a graphic of Robotnik's name on and unaccessable.
  • The list of characters after the Diamond Maze game haven't been implemented yet.
  • There is a delay between revealing the contents and controller the character in the Diamond Maze. The mini game is also harder due to this.
