I’m sorry, I wasn’t completely clear. Yes you can run games on ARM on any OS with an emulator. When I said “won’t run any better” I meant you’ll get the same emulation slowdown on Linux as on Windows.
The point of the article is that stuff runs faster on Linux because you don’t need an emulator, and it implies that that includes games. That’s disingenuous because any games that require emulation on Windows will also require emulation on Linux. If there’s no ARM build, there’s no ARM build.
Or enabling nix-ld can often get such binaries working.
