Kaizo Mario Bros 3Description

Don’t think this is gonna be a 100% Gold Remake, it’ll have its differences. Extra battles (some’ll be optionals, tough but rewarding), Hoenn Pokemon (in every area, and hard to find) New areas, Remapped some dungeons (so your old guides wont work) , Extra recurring characters (some’ll hate you, some’ll help you)

Note that the hack is incomplete but feel free to enjoy the hack as-is.

Kaizo Mario Bros 3 holds true to Kaizo's themes and roots, while utilizing the fantastic mechanics and underutilized suits of SMB3.  KMB3 is a mod designed to test the most skilled SMB3 players.

Kaizo does not want you to win.  Kaizo wants you to lose, and it will troll you.

Special thanks to all the SMB3 speedrunner community, T. Takemoto for creating the Kaizo series, and of course to Miyamoto and Nintendo for creating the culture that we all found ourselves a part of.
