The Winlator-releated ecosystem already works pretty well, there just isn't a good frontend or integration for it yet. That's what is really exciting here.

Gamehub is a proprietary app by a Chinese controller manufacturer with some suspicious behavior and several LGPL violations that unfortunately works much better then the alternatives. Funnily enough their CDN endpoint is called "bigeyes", which when researching a bit was apparently their (failed) effort to bring x86 VR to ARM almost 10 years ago. Some people have "debloated" the app, but it seems very amateur hour to me and the process isn't very transparent (the GitHub repo is just a readme)

There's also GameNative, which seems promising, but is very buggy.

And Winlator itself, which is a mess of tons of tunables and different forks that I really don't have the patience for when PC handhelds exist today and have a much better ecosystem.
