It can use FEX to run x86 binaries, or use ARM binaries directly in steam for games that have them (games that support apple silicon macs, for example) and it can sideload apks meant for android, if the apk is actually standalone, and doesn’t have system dependencies that only exist on meta devices.

I honestly wonder how much of this is just copied over from the functionality they wanted on the steamframe. because there it’s a great, potentially fantastic tool, where as on the steam machine it’s… interesting?
