so, today is the twenty-fifth anniversary of the original release of Super Mario Bros. there’s no better way to celebrate than with romhacks! you’d do well to seek out the following and play them in your favorite NES emulator:
Extra Mario Bros. is a Metroid tribute made in the Super Mario Bros. engine. running through a Metroid-like map with all the limitations of Mario (you can only go forward) is kind of a trip. play it!
Super Luigi Bros. is just kinda messed up.
Silhouette Enigmario Bros. is actually two hacks patched together, check it out.
Play them all! Find some others and comment here!
