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.

This hack alters all of the original game's levels, and features some modified enemy behavior. It's not super difficult but some of the later levels can get a little challenging. Overall though its harder than vanilla SMB but easier than the Lost Levels. This was essentially made from messing around with some of the SMB hacking utilities so don't expect anything too crazy.

Features

-32 new levels
-wacky new color palettes!
-faster, harder enemies
-weird glitchy warp zones
-more secrets maybe?
