EDS Mario

EDS Mario is an unofficial ROM hack of one of the Super Mario Bros. games for the NES (Dendy) with modified levels, changed sprites or reworked content.

Hacks like this are created by fans with level editors and are their own interpretations of the classic. Mario runs, jumps on enemies, collects power-ups and heads for the flag at the end of each level.

It is a curious find for fans of Mario.
