PlayStation 4 emulators
There is one PS4 emulator in very early development PS4EMX. Even though the PS4 does have an x86 CPU like normal PCs, it doesn't mean it'll be easy to emulate as the x86 instruction set is huge. However, nearly all of x86 instructions are well documented (though some other specifics aren't) so the possibility is there. Another thing is there is currently no documentation on the GPU used in the PS4's APU and the console isn't hacked - please don't even ask about PoC emulators until it's hacked. All that said, don't expect any functional PS4 emulators for a very long time, like 10 years.
