I’m surprised I haven’t heard more of this (makes me think its impossible), but I feel like the ideal world is buying big tech’s hardware and overriding its firmware/software to talk to home assistance locally. I saw a post recently about someone making an google nest speaker work with home assistance and they really just made their own speaker and shoved it in a nest mini body. I like the hardware I have, I just wish I had more control over it, and sadly I don’t know nearly enough to mess with firmware myself.
Yuzu is an interesting idea, I haven’t thought of that, but last I checked a few months ago, it was still not working, and I heard using wine to run the windows version can get you banned so I never tested it.
On my steam deck I’ve been using Xbox cloud gaming (free if you’re willing to wait) or Amazon Luna (if you have prime), and they work decently well, much better than “not running at all”.
