What MeltyTool is
MeltyTool is a free Windows multitool for viewing and extracting assets in bulk from supported N64, GameCube, 3DS, and PC games. Its WinForms interface lets users browse supported models and view renderings intended to approximate their appearance in the original game. Users can extract models from a directory, with progress displayed while the work runs in the background, and separate batch scripts are provided for supported games. A command-line utility converts model files and selects a plugin based on the input. Model exports are produced in GLTF/GLB and FBX formats; the listed asset types also include textures, animations, rigs, maps, audio, MIDI, and Picross puzzles. Supported titles include Paper Mario, Super Mario Sunshine, Pikmin, Super Smash Bros. Melee, and several Zelda games. The usage guide directs users to extract the download and launch the interface with a Windows .bat file. The repository recommends release downloads for stability, or using its Code button for the latest version. Some models or features may not be supported or accurately recreated, and exported materials may need manual repair in an importing program.
