Super Mario Bros. is a platforming game for the Nintendo Entertainment System released in 1985. When Bowser invades the Mushroom Kingdom, it's up to Mario to stop him and save the Princess.

A level (and text) hack for Super Mario Bros. made with SMB Utility. The patch was created with "xdeltaUI". The hack consists of 4 levels (replacing 1-1 through 1-4). The aim was for the easy side of "kaizo light" (with some minor trolling), but seasoned players should have no challenge getting through the levels in a hour or less. There is a slight graphical glitch upon clearing 1-3 - if anyone knows the cause of this please share your knowledge! Most importantly, thanks for checking out the hack and hope you get some enjoyment out of it.

Change notes:

V1.1: Shortened the timer in 1-1 to prevent a glitch in which, if the player were to ride the moving platform across the goal, the game would freeze.

V1.2: Altered an obstacle in 1-3 to prevent an unintended method of clearing the stage, and added a small pit to facilitate retrying the stage.

V1.3 (current): Added a custom BGM track (composed by JonnyManjiro) that is played on stages 1-2 and 1-4.
