The original Sonic The Hedgehog that busted the speed barrier wide open on the SEGA Genesis is coming to the Game Boy Advance. For the first time, you'll be able to save your high scores and progress as you rocket through the seven gravity-defying stages that started it all. After you outrun Dr. Robotnik and his badniks in Original Mode, race through the famous loop-de-loops even faster with Sonic's trademark Spin Dash in Anniversary Mode which celebrates Sonic's 15th birthday.
