Game Trivia

  • There are a few minor graphical differences between the US/EU and Japanese releases of the game. The clouds of the Green Hill Zone move along in the sky in the Japanese version (whereas in the other versions they stay still), and the water of the Labyrinth Zone has a gentle rippling effect that slightly distort anything submerged to give it more of an underwater "feel". Also, the Level Select screen has the order of the zones fixed into the correct order.

  • The game's instruction manual lists a 1-Up as a collectible item in the Secret Zone (its picture is that of a bright circle with a picture of Sonic inside it). This item is nowhere to be found within the game, however it was originally included during development as it can be accessed with the use of the debug mode cheat.

  • Of all places, Soinic the Hedgehog has a glitch at the title screen! At the title screen, the text "Press Start Button" was intended to appear, but doesn't. It uses the same chunk of memory as the "Sonic Team Presents" screen, which doesn't clear properly after the screen fades, preventing the "Press Start Button" text from appearing.

  • Sonic the Hedgehog was created and tailored to appeal to SEGA's US market - despite being designed by the Japan team. This followed on from SEGA of America's aggressive "SEGA does what Nintendon't" advertising campaign which surprised and somewhat inspired SEGA of Japan to go more head to head with Nintendo

  • The initial concept of Sonic the Hedgehog was a more traditional platformer with puzzles and exploration akin to Super Mario Bros. 2. The final product, while still a platformer, focused more dominantly on its now trademark speed. This evolution is even more prominent in its sequel.
