Plays inside your own copy of Minecraft: Java Edition, on your device, not in a browser tab. Opens github.com in a new tab.
How to play
Have your own copy of Minecraft: Java Edition installed: the mashup plays inside it.
There is no release yet: get its code from its repository on GitHub and build it as its README says.
Install it as its page says. What it asks for is just below, in the list's words.
Start the game the way its page says: some mashups come with a launcher of their own.
What it asks for
Minecraft 1.21.1 with NeoForge 21.1.x, an extracted Xbox 360 copy of Skate 3 (default.xex plus data folder, not an ISO), and Python 3.11+ with numpy and Pillow for the one-time conversion; a controller is recommended.
