Actually shadPS4 is a compatibility layer. What it does is re-implement the PS4 libraries and translate PS4 shading language into SPIR-V.
shadPS4 is emulator

and fpPS4 is compatibility layer

check this wiki for more info : https://emulation.gametechwiki.com/index.php/PlayStation_4_e...

Those wiki has some incorrect information. How shadPS4 and fpPS4 works are the same. Almost of them can be categorized as a compatibility layer. The only one that can be called a PS4 emulator is Orbital because it virtualize (and emulate) the PS4 hardwares.
