Play Super Mario 2 1998 (Unl) Online

Summary

Super Mario 2 1998 (Unl), sometimes whispered as Sonic Jam 6, is a curious unlicensed port that lifts the Super Mario All‑Stars remake of the original Mario 1 straight onto the Genesis. I can’t help but notice how the physics feel oddly clunky, as if the code was rushed, and the sound effects are heavily compressed, giving the whole experience a tinny edge. The Sonic Jam 6 variant throws a twist into the mix by swapping Mario for Sonic, but it also strips away the classic two‑player mode, leaving the solo run as the only option. It’s a strange piece of retro history that feels more like a rough draft than a polished release.
