Play Boris (super mario world hack) Online

Boris is a Super Nintendo Entertainment System (SNES) hack of Super Mario World, released as a fan modification with no official publisher or developer credits. It belongs to the expansive library of ROM hacks that reimagine classic platformers, often twisting familiar elements into something surprising and strange.

You control Mario through a series of levels that remix assets and enemies from the original game, with the goal of simply surviving and reaching each flagpole. The hack introduces unexpected enemy placements, hidden passages that warp you into bizarre rooms, and screen by screen exploration that demands careful observation. The pacing is brisk, and the difficulty can spike without warning, but the challenge usually feels more absurd than unfair. Playing Boris is like navigating a funhouse mirror version of a game you thought you knew.
