The original Sonic The Hedgehog™ that broke the speed barrier wide open on the SEGA Genesis is now on the Game Boy Advance! The game has seven original gravity-defying stages that have been perfectly ported over to let players experience this classic on Game Boy Advance. Navigate through loop-de-loops of Green Hill Zone, zoom past waterfalls, and dash over molten lava at Sonic's trademark super speedy pace while collecting gold rings.
