Mario Builder 64
Mario Builder 64 is essentially Super Mario Maker for Super Mario 64. Created by Rovertronic, this revolutionary ROM hack adds a fully functional in-game level editor to Super Mario 64, allowing players to design, build, and share their own 3D Mario levels. Players can place platforms, enemies, objects, and terrain directly within the SM64 engine, then publish their creations for others to play — a concept that fans have dreamed about for years.

What Makes Mario Builder 64 Special?
No one thought an in-game level editor was possible within Super Mario 64's engine, but Rovertronic proved otherwise.
Mario Builder 64 lets you build 3D levels using Mario 64's own objects and mechanics — place Goombas, Bob-ombs, platforms, coins, and terrain tiles in a 3D space, then immediately jump in and test your creation. This is fundamentally different from traditional ROM hacking, which requires external tools and technical knowledge.
The editor is accessible enough for beginners while powerful enough for experienced level designers. A sharing system allows creators to distribute their levels, building a community around creation and play. The project continues to receive updates that add new objects, features, and quality-of-life improvements.
