Recently In recent years many of [https://www.playstation.com/en-us/games/pc-games/ PlayStation 4 era (Pro) exclusive titles are now being ported to PC ] with [[#Enhancements|enhancements]] already, so similar to [[PlayStation_5_emulators#Emulation_issues|PlayStation 5]], [[Xbox One emulators#Emulation issues|Xbox One situation(X|S)]] and [[Xbox_Series_X_and_Series_S#Emulation issues|Xbox Series X|S]] situations this '''could''' lead to a decreased interest in development. Having said that, there are still considerable amount of games exclusive to those consoles, this includes games for both PlayStation 4 (Pro) and Xbox One (X|S) that haven't been ported and titles lacking enhanced/next-gen update for PC. See [[List of notable ports#External_links]] section for all of those games.

:; PlayStation 5
:: Placeholder textThe PlayStation 5 boasts extensive backwards compatibility with a vast library of PlayStation 4 titles. [[PlayStation_5_emulators#Hardware_features_and_peripherals|This functionality]] allows users to play the overwhelming majority of physical PS4 discs and digital games downloaded through the PlayStation Store directly on their PS5 console. Additionally, some PS4 games may benefit from [[#Enhancements|enhancements]] on the PS5 hardware (similar to PlayStation 4 Pro) if it supports "Game Boost" option, such as experiencing higher or more stable frame rates.

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.
