→Emulation issues
Due to the PS4's [[POS_(Pong_Consoles)_CPUs_and_Other_Chips#x86_CPUs|x86 architecture]] and FreeBSD-based operating system, emulators for the device will, by and large, be very unconventional. Despite the x86's instruction set being huge<ref>{{cite web | url= https://en.wikipedia.org/wiki/x86_instruction_listings | title= x86 instruction listings | Wikipedia}}</ref>, a trait that would typically lead to years of development time by emulators, it opens the ability for pre-existing hypervisors to do the heavy lifting, eliminating the need for a recompiler. There is also, as of this time, little to no documentation on the GPU (a modified Radeon 7970M with disabled stream processors) used in the PS4's APU, and it will require a complete re-implementation by emulator developers.
In recent years many [https://www.playstation.com/en-us/games/pc-games/ PlayStation 4 (Pro) exclusive titles are now being ported to PC] with [[#Enhancements|enhancements]] already, so similar to [[Xbox One emulators#Emulation issues|Xbox One situation]] this '''could''' lead to a decreased interest in development.
