Loading the game…
Press Enter on the title screen to enter Green Hill Zone. Build momentum, collect rings, and jump onto enemies.
Gamepads and on-screen touch controls are supported. Keep at least one ring to survive a hit. Hold Jump longer to jump higher. This is the original Sonic 1: roll while moving; there’s no standing spin dash.
A noncommercial fan modification of the 1991 Sega Genesis game. Jahmyr Gibbs replaces Sonic and holds a football on the title screen. The boss roster features Matt LaFleur, Kevin O’Connell, Ben Johnson, Aaron Rodgers, Matt Patricia, and Matt Millen. Each boss keeps the original encounter’s movement, attacks, and weapon patterns. Levels, music, and regular enemies remain from the original game.
Built from Sonic Retro’s Sonic 1 disassembly. Browser playback uses EmulatorJS and Genesis Plus GX. Runtime licenses
