WARNING!!!!

this tested only on my laptop, with not last snapshot

My kernel:

kern.version=OpenBSD 8.0-current (GENERIC.MP) #123: Fri Oct 23 07:33:43 MDT 2026
    deraadt@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP

So, let's try

normal patch of prismlauncher will be soon I think, but this tutorial can also be useful

26.1 works out from the box with lwjgl3-3.4.1.0(for 26.x you MUST need to have it)

for newer than 26.1 you need to edit

<PrismLauncher_DIR>/instances/<INSTANCE_NAME>/patches/org.lwjgl3.json

my config is here

If you have sodium mod, you must set this java argument:

-Dsodium.checks.issue2561=false

also, you might need sdl3 for 26.x minecraft

this is all I needed to launch it, but as I said before, this should be patched in prismlauncher port a bit later.
