MCPI-Reborn Dockerless build.

README.md

Minecraft Pi Reborn - Dockerless build

Warnings

Only for RPis - Tested on a RPi 4B - You still need Full/Fake KMS - Not magic. Conflicts with minecraft-pi-reborn-* Unsupported - Use at your own risk.

Script(s) to build MCPI-Reborn without Docker.

dockerless-build.sh gets MCPI-Reborn, applies some patches (in the dockerless.diff file, you have to download it too), and builds it without the Docker dependency. The resulting DEB will be placed under minecraft-pi-reborn. Then you can install it and run minecraft-pi or try to use MCPIL to launch it (it should be compatible).

This might or might not work on your machine, it works on my machine:tm:, but I thought maybe someone could find it useful, since it speeds up MCPI a bit.
