FAQ
What is a mashup?
A mod that joins games into one. In SkyCraft, you play Skyrim as a Minecraft player.
Do I need the games?
Yes. Mashups run on games you own. If you are missing one, Melty sends you to its store.
What does Play do?
It downloads the mashup, installs what it needs, and starts the game. Uninstalling puts every file back as it was.
Can I play with friends?
Yes, on multiplayer mashups. Press Play to get an invite link, then keep it private, share it, or go public.
Can I make my own?
Yes. Copy Melty’s instructions into Claude Code or Codex and say what you want. The agent builds it and publishes it.
