Play Mario DG Sonic Bros (SMB1 Hack) Online

Game Overview

Mario DG Sonic Bros (SMB1 Hack) is exactly what it sounds like—a weird but fun mashup of classic Mario platforming with Sonic's speed and visual style. The first thing you notice is how fast Mario moves, almost slippery, like he's on ice. It takes some getting used to.

The levels are familiar but tweaked—some pipes lead to different places, enemies behave oddly, and the physics feel just slightly off in a way that keeps you on your toes. The Sonic-inspired sprites are a nice touch, though some of them clash with the NES aesthetic.

It's not perfect—some jumps feel unfair due to the speed, and the collision detection can be janky. But if you're into ROM hacks that mix things up, Mario DG Sonic Bros (SMB1 Hack) is worth a try for the novelty alone.
