Play Super Mario Yaji World Online

Super Mario Yaji World is a fan-made ROM hack for the Super Nintendo Entertainment System, released unofficially. It takes the familiar engine of Super Mario World and contorts it into a bizarre, unpredictable experience, feeling like a strange, alternate version of a game you thought you knew.

You control Mario through a series of heavily modified levels where the core mechanics are deliberately broken. Grabbing a fire flower makes Mario sneeze erratic fireballs that fly in random arcs, and P-switches turn blocks into bouncing, unstable objects instead of coins. The main objective remains to simply reach the goal, but the journey is defined by navigating these intentionally faulty systems. The pacing is frantic and the difficulty is high, not from precise challenges but from the sheer unpredictability of your own tools. Playing it feels like trying to run a marathon while your shoes are actively trying to trip you.
