One Play starts Cyberpunk with portable Minecraft hidden in the background.
Melty starts Cyberpunk 2077 directly from Cyberpunk2077.exe and launches a bundled portable Prism Launcher alongside it. The portable instance includes CyberCraft for Minecraft 26.3, Fabric Loader 0.19.5, Fabric API, and e4mc. CyberCraft keeps the Minecraft instance in the background so its gameplay can blend into Cyberpunk.
On the first Play, Prism opens once for Microsoft sign-in with an account that owns Minecraft: Java Edition. After that, one Play starts Cyberpunk and the bundled instance together. The remix does not depend on an existing .minecraft folder.
