This in combination with the 3D acceleration work going into QEMU [1] could end up being a pretty compelling solution for running the x86 Linux version of Steam on macOS.
I was under the impression that Box86 would not work on the M1 because it wants to run in 32 bit mode, and Apple did not implement 32 bit mode on their processors.
