You need a custom kernel, or a kernel module plus DKMS and kernel headers for your current kernel.
You also need the package that handles whatever filesystem they use for their containers.
Then, you need to be running it on Wayland or else it doesn’t work.
The part that I’m stuck on is running games, which gives an error about not being able to find libmain.so, which might be an architecture mismatch problem. Maybe I can virtualize that part? But at that point I might as well just buy a phone.
