Short answer
Super Mario Bros. Remastered is a free, open-source fan remake of the NES Super Mario Bros. games, rebuilt in Godot for Windows and Linux (Mac through an unofficial fork). It covers SMB1, The Lost Levels and two rare variants, with better physics, resource packs and a full level editor. It needs a ROM of your own SMB1 cartridge. Latest release: 1.1, 4 September 2026.

What it is
Super Mario Bros. came out on the NES in 1985. Nintendo sells it today only as part of Nintendo Switch Online and other official re-releases, never as a PC game.
Super Mario Bros. Remastered is “a Remake / Celebration of the original ‘Super Mario Bros.’ games”, featuring “new levels, custom modes, new characters, alongside a full level editor / custom level system” (SMB Remastered README). It is not an emulator or a recompilation: the levels and gameplay were recreated from the ground up in the Godot engine. It loads the original graphics and sounds from your own ROM, so the repository ships none of Nintendo’s assets.
The README is explicit that it “does NOT act as a replacement for the original Super Mario Bros. games”.

How to start
- Download the zip for your system from the releases page.
- Extract it and run the game.
- When asked, select your Super Mario Bros. NES ROM so it can load the original assets.
- Pick a game (SMB1, The Lost Levels, Special or All Night Nippon), a custom mode, or the level editor.
Create an empty file called portable.txt next to the program to keep settings and saves in the same folder.

Other versions
The only other active Super Mario Bros. project in our list is SuperMarioBrosNESRecomp, a static recompilation experiment from the R.A.I.D. community that turns the NES code into a native program. It is a technical project rather than a remake. The full list of versions, including the SMB disassemblies the community uses for research, is above.
