🎮 Play Smb1 Mario In Sonic The Hedgehog Online (Sega Genesis)

Smb1 Mario In Sonic The Hedgehog is a crossover ROM hack for the Sega Genesis that replaces the star of Sonic the Hedgehog with Mario from Super Mario Bros.. Players can experience the familiar loops, springs, and layouts of South Island’s zones while playing as Nintendo’s iconic plumber instead of the blue blur.

How to Play

The game uses standard Sega Genesis controls, mapped to your keyboard for the browser. Use the D-pad (Arrow keys) to move Mario through the levels. Press A, B, or C (Z, X, or C keys) to jump over obstacles and defeat enemies. Press Start (Enter) to pause the game.

Tips

Because the levels in Sonic the Hedgehog were originally designed for speed and momentum, playing as Mario requires a different approach. Take your time navigating the environments, and rely on precise jumping rather than rushing forward, as Mario cannot use Sonic’s spin dash or rolling attacks.
