Proton technically isn't emulation, but it's pretty crazy that the device basically doesn't have anything natively built for it, everything is translated emulated. It took that much effort to break Microsoft's PC gaming monopoly.
Regardless of what the website says, waydroid isn't an emulator by any meaningful definition.
It's a container that runs on top of your regular linux kernel (with some very cool desktop integration features), java/kotlin applications run as natively as they'd run on your phone.
Uhh.. for their steam deck I'd think 😂 not that it'd be a primarily mobile gaming device, but no reason not to put your mobile games on it if you like them
Still pisses me off, this was one of the reasons I updated and they half-assed the implemenation then said they're killing it because no one is using it... no shit no one is using it, you hid it it behind the Amazon App (that no one uses) in the MS Store (that no one uses) and layers of docs for sideloading.
Hmm something about this has me fantasizing about a phone sized deck. But considering Valves development of VR and this development, I think they are going to tap into the android based VR dev pool for porting titles to an official Android on Steam platform.
Valve makes infinitely more money off of store fees selling other people's games. Why would they want to make a fraction developing a single game when they can go after Android's 30% cut?
