Super Mario Bros. Definitive

What it is

Super Mario Bros. Definitive, by Simplistic6502 and web2000, puts every level of Super Mario Bros. and of the Japanese sequel (The Lost Levels) into a single NES game. You play the 32 stages of the first game, then go straight into the sequel.

What's new

• A new World 9 for the first half, built from the original's glitch levels, with a 9-4 maze borrowed from Vs. Super Mario Bros.
• Worlds A to D of The Lost Levels made harder in the way Super Mario All-Stars did, and Bowser breathes fire there
• Bug fixes from All Night Nippon Super Mario Bros., and no more getting stuck at the end of water areas, as in the European release
• Five lives to start and after a Game Over, with a capped and correctly shown life counter
• Luigi gets All-Stars handling and his own palette; Lost Levels physics apply throughout
• A few visual changes, such as a night-time snowy 3-3

Version 1.3.1 (December 2024) adds animated water and more fixes.
