Play Super Mario Adventure (SMB1 Hack) Online

Game Overview

Super Mario Adventure (SMB1 Hack) is one of those NES romhacks that actually feels like a proper sequel. The levels are completely redesigned—some are brutal, others have clever little secrets tucked away. You'll recognize the mechanics, but the layouts keep throwing curveballs.

First thing you notice? The enemy placements. They're not just reskins—some behave differently, like Goombas that take an extra hit or Piranha Plants with weird timing. Took me a few deaths to adjust. And the warp pipes? Half of them lead somewhere unexpected, which is equal parts fun and frustrating when you're just trying to progress.

It's still Mario at its core, but Super Mario Adventure (SMB1 Hack) makes you rethink muscle memory. That’s the best part.
