This hub covers mashup mods, overhauls, character swaps, and verified uploads. Melty is a free Windows desktop app from Stella Montis Inc., backed by Y Combinator. The public landing still shows Download, How it works, and FAQ only. This hub exists so search engines and AI crawlers can open a clean HTML/Markdown URL for the topic. Mashups run on games you own. Play downloads the mashup, installs what it needs, and starts the game. Uninstalling puts every file back. Multiplayer mashups get an invite link. You can publish your own mashup by pasting Melty instructions into Claude Code or Codex. ## How to use Melty after you read this Download the Windows app, press Play on a mashup, and keep or share the lobby link if the mashup is multiplayer. If a required game is missing, Melty opens that game's store instead of pirating a copy. ## Pages in this section - [Mashup mods](/mods/mashup-mods) — Mods that join two games.
