Super Mario in Sonic the Hedgehog 1 is a clever ROM hack for the Sega Genesis that swaps out the iconic blue blur for Nintendo’s famous plumber. Instead of speeding through the zones of the original game as Sonic, you control Mario. The hack adapts the fast-paced level design to accommodate Mario’s traditional platforming mechanics, creating a fascinating crossover that blends two classic franchises.
How to play
Your goal is to reach the end of each act and defeat Dr. Robotnik. Unlike Sonic, Mario relies on his jumping skills rather than rolling into a ball.
- D-pad / Arrow Keys: Move left and right. Press Down to duck.
- A, B, or C / Z, X, or C: Jump. You can defeat most badniks by stomping on them.
- Start / Enter: Pause the game.
Tips
- Mario does not have Sonic’s spin dash or momentum-based rolling. Take your time and approach loops and steep hills carefully, as the physics feel different.
- You still collect rings to protect yourself from taking damage, so grab as many as you can before tackling tricky platforming sections.
