SMB1 Mario in Sonic The Hedgehog
About SMB1 Mario in Sonic The Hedgehog
SMB1 Mario in Sonic The Hedgehog is a ROM hack for the Sega Genesis that replaces Sonic the Hedgehog's sprite with Mario from the original Super Mario Bros. It's a fan-made modification, not an official release, and its creator is unknown. The hack gained some attention in the early 2000s as part of the grassroots modding scene for classic 16-bit games, though it remains a niche novelty rather than a polished standalone title.
Playing this hack feels exactly like the original Sonic the Hedgehog, but with Mario visually swapped in. You run through Green Hill Zone and beyond, collecting rings, defeating badniks, and racing to the end of each stage. The physics and level layouts are untouched, so Mario's jumping and speed behave identically to Sonic's. The only real difference is the character model and some palette changes to accommodate Mario's look. No new mechanics or story are added - it's strictly a cosmetic reskin.
For fans of both franchises, this hack offers a silly what-if scenario that can be amusing for a quick playthrough. It's not a deep or transformative experience; the novelty wears off fast. If you enjoyed the Genesis original and want to see Mario zipping through loops, it's worth a look. But keep expectations low - this is a simple sprite swap, not a full crossover game. It sits in the library as a curiosity rather than a must-play.

How to Play SMB1 Mario in Sonic The Hedgehog Online
Getting Started: Launch the game and press Start (Enter) to begin. You'll be placed at the title screen where pressing Start takes you into Green Hill Zone. The core gameplay is identical to Sonic the Hedgehog: use the D-Pad to move left or right, hold down run to dash, and press jump to leap over obstacles and onto enemies. Collect rings to protect yourself from damage - losing all rings means instant death.
Your goal is to get through each act as quickly as possible while avoiding hazards like spikes, pits, and enemy attacks. The hack doesn't change any level designs or enemy placements, so if you know Sonic, you know this. There are no new power-ups or mechanics; Mario simply runs with Sonic's speed and physics. The game ends when you complete all zones, just as in the original.
Since this is a straightforward sprite hack, there is no language barrier or complex menus. Everything is in English (the original game's text remains). If you've never played Sonic before, the basics are: keep moving right, jump on enemies to destroy them, avoid water and bottomless pits. The most important tip is to memorize level layouts to maintain momentum, as stopping can be risky in later zones.
