SMB Ultimate Edition 3

SMB Ultimate Edition 3 is a fan-made ROM hack of the original Super Mario Bros. for the NES (Dendy).

Like other hacks in this family, it keeps the familiar mechanics but changes the levels, enemy placement and sometimes the graphics, making the game noticeably harder than the original. Mario still runs, jumps, collects power-ups and heads for the flag at the end of each stage.

It is a challenge for experienced players who know the original by heart.
