Melee Mod Studio

Melee Mod Studio is a modding workbench that runs entirely in the browser. It opens a copy of Melee that you already own through the File System Access API and edits it in place: character attributes and move scripts, costumes and portraits, stages, music, and 3D models. Every file format involved is parsed by code written for this project, from the GameCube disc image itself down to the texture and audio codecs, and the game data never leaves your machine. On top of the editor sits a marketplace of community cosmetic mods backed by Cloudflare D1 and R2, with thumbnails rendered from a mod's own model file in the visitor's browser when it ships without artwork.

Attention: You need your own legally dumped copy of the game, and a Chromium browser such as Chrome or Edge, because the workflow depends on the File System Access API. The app does not host or distribute game files.
