SMB3-RS

What SMB3-RS is

SMB3-RS is a browser-based randomizer for Super Mario Bros. 3. It rebuilds each world map, rather than only changing level order, and can randomize power-ups, enemies, chest items, and palettes. You provide your own Super Mario Bros. 3 (USA Rev 1) ROM; it stays on your machine while the randomizer runs. The tool creates an IPS patch or a patched ROM. A seed and flag key let players reproduce the same game, and entering another player's flag key recreates their settings, making shared races possible. The browser version runs on Windows, macOS, Linux, and mobile without installation. The repository also offers a native command-line tool for batch testing and debugging. SMB3-RS is open source and lists an MIT license. The project directs bug reports to GitHub issues with the run's seed and flag key. Its page does not state a price or whether a free plan is available.
