Frank's 2nd Super Mario Bros. 3
Frank creates a new Mario Bros. 3 experience.
Created By: Frank Maggiore
Game Info:The levels in this new Super Mario Bros. 3 are vastly different from the original game and feel like a completely new experience! Levels don’t start out terribly difficult, but get tricky later on, though they never become unfair. Secrets are strewn throughout the many levels, including new levels for the White Mushroom Houses, with new coin requirements, and the hidden whistle.
Other Notes:While it's certainly possible to play through Frank's 2nd Super Mario Bros. 3 in one sitting, chances are you're going to want to save. If you would like the ability to save your progress, you can download an NES Emulator and the Frank's 2nd Super Mario Bros. 3 ROM patch which are found on the main Super Mario Bros. ROMs page.
To begin playing, you must click the game screen with your mouse. Then the keyboard controls will work.
