How to build ISO file

Preparing minceraft

At first, you need to prepare minceraft.

Minceraft preparing consists of 5 steps:

Copying UltimMC configs to data/mine dir
Building and copying mods to MC instance
Compiling UltimMC from source (if you want to skip this step, you only need to copy built release of UltimMC to ultimmc/build directory)
Downloading assets and libraries (just launches instance in online mode)
Copying UltimMC configs again

Use mkmine to do all this automatically:

./mkmine

# IMPORTANT: if you get java selection window, choose Java 21

Use mkiso script to create ISO file. Result will be in the output/ directory.

Script compiles it only for x86_64, but I think it's not really hard to make it compile for any other architecture

This script only work on Void Linux (because it needs XBPS).

sudo ./mkiso

# idk why it needs sudo, please pr if you know how to remove it

Finally, you can forget all above and use just [ -d data/mine ] || ./mkmine; sudo ./mkiso
