Hack of Super Mario Bros.


This MMC3-based freeplay hack let’s the player choose between Super Mario Bros. and Super Wario Bros.

NOTE: Levels are completely untouched and can be freely selectable by the respective button!

NOTE 2: Mario, Luigi, Wario and Waluigi have separated fiery palettes!

NOTE 3: The ending text has been rewritten!

Features of Super Wario Bros.:

  • Can be selectable if the player pushes the Down button on the title screen (if Down is pushed again, it changes back to Super Mario Bros.)
  • Game is in hard mode
  • The player is not able to use A + Start
  • Worlds can be selected by pressing A
  • The musics and the sound effects are gloomy and sour
  • The bonus room’s cloud has evil smile
  • The palette of the level styles and their background colors are darker and different

Enjoy and have fun!
