Has anyone tried it yet? I can't imagine that the Steam Deck has the required performance to emulate the PS4.

Most games have too bad of performance to work properly. The Bloodborne focused fork reportably gets 25-30fps, but that's with some mods and system tweaks.
A consistent 30 fps would be great
Does this mean there are ps4 emulators?! I didn’t think it was possible for some reason
It's impossible because emulation technically implies that there are hardware differences between the two systems, and the PS4 is literally just a PC with a special OS. My understanding is that PS4 emulation is more like Wine than a true emulator
My impression of emulation's definition is that its purpose is to mimic the real thing as closely as possible vs something like simulation where it's more to get an impression of the target system or mimic specific portions. I don't think the architecture has to be different for something to be emulation.
There’s not much hardware to emulate rather the software. X86 is probably the target.
I'd argue exposing and implementing all the APIs PS4 games expect to exist and in the way they expect them to behave is just as much emulation as translating CPU instructions.
They're barely even emulators. The PS4 was basically just an x64 PC with an AMD 7000 series GPU
Oh wow, ok. Time to go down a rabbit hole!
Yep, although quality is mixed depending on the game.
what is different in the fork? it looks lile yet another fork where they don't detail its purpose or differences anywhere and use the exact same readme and other text as the original.
The fork is specifically focused on Bloodborne only emulation, and has significantly improved performance in that one specific game. I don't know any specific listed changes for it, just that people report significantly better performance on it.
