Super Jario Bros.

Hack of Super Mario Bros.


This is a ROM hack of Super Mario Bros. starring plumbers Jario and Duigi. Choose either Jario and Duigi, each equipped with a different set of physics, and set out to save the Mushroom Princess from King Trowser. In their quest, they will have to journey through four brand-new worlds filled with new set pieces and enemies lurking around every corner. Do you have what it takes to rescue the Mushroom Kingdom?

v1.1 Revision Details:

  • Errors with 4-4 ending sequence corrected (Mushroom Princess and all ending text now appear).
  • World select is no longer enabled after completing 5-1 in order to keep the All Levels route more interesting.
  • Duigi is no longer erroneously referred to as Jario on the Game Over screen.
  • Trowser no longer appears as a Spiny when killed with fireballs.
  • Minor change to World 4-3 made to prevent player from possibly being stuck until a time up.
  • New inputs recorded for the title screen demo.
