Sonic The Hedgehog Game Genie Codes (USA, Europe)
This page contains the Game Genie codes that I have for Sonic The Hedgehog (USA, Europe), a game for Sega Genesis. If you're using an emulator you will be able to input the codes found on this page directly into the program and use them. For those of you who are old school and playing on a physical console, you'll have to purchase a Game Genie device to use them.
If you don't see the code you want on this page, I recommend you return to my Sonic The Hedgehog Guides Index and choose a different section.
