The '''PlayStation 4''' (PS4) is an eighth-generation console produced Games marketed by Sony Computer Entertainment as PS4 Pro Enhanced have specific optimizations when played on November 15, 2013this model, such as 4K resolution graphics and retailed for {{Inflation|USD|399/or higher performance.99|2013}}For games not specifically optimized, an option known as "Boost Mode" was added on system software 4. It is the first PlayStation console 5, which can be enabled to force higher CPU and GPU clock rates on existing games to use the possibly improve performance.[[wikipediahttps:x86|x86]] architecture, a semi-custom 8-core AMD Jaguar CPU at 1//en.6 GHz. One of the cores is utilized separately only for low-power background tasks. The CPU shares its place on an APU chip alongside a semi-custom AMD GCN Radeon GPU supported by 8 GBs of GDDR5 RAM at 2.75 GHz, while 256 MBs of DDR3 RAM is used only for background taskswikipedia.org/wiki/PlayStation_4#PlayStation_4_Pro]

Emulating the PlayStation 4 (Pro) will prove to be a monumental task owing to the complexity of x86_64 and the Radeon-based GPU. Most projects will inevitably end up going the route of [[Wine]].

For games not specifically optimized, an option known as "Boost Mode" was added on system software 4.5, which can be enabled to force higher CPU and GPU clock rates on existing games to possibly improve performance. Rendering games at 4K resolution is achieved through various rendering techniques and hardware features; PlayStation technical chief Mark Cerny explained that Sony could not "brute force" 4K without compromising form factor and cost, so the console was designed to support "streamlined rendering techniques" using custom hardware, "best-in-breed temporal and spatial anti-aliasing algorithms", and "many new features from the AMD Polaris architecture as well as several even beyond it". The most prominent technique used is checkerboard rendering, wherein the console only renders portions of a scene using a checkerboard pattern, and then uses algorithms to fill in the non-rendered segments. The checkerboarded screen can then be smoothed using an anti-aliasing filter. Hermen Hulst of Guerrilla Games explained that PS4 Pro could render something "perceptively so close [to 4K] that you wouldn't be able to see the difference".[https://en.wikipedia.org/wiki/PlayStation_4#PlayStation_4_Pro] ==Dissidia Final Fantasy Arcade variant==Taito's Dissidia Final Fantasy Arcade is the only arcade game that runs on PS4-based hardware. This game runs on a PS4 kiosk demo unit, and the hardware is identical to regular retail PS4 and could be converted to regular retail mode. An extra I/O board is attached to the PS4 via a USB port. Despite the fact that the arcade game program itself could run on a regular PS4 without any issue, the USB I/O board is yet to be reverse-engineered, and judging from the current status of PS4 emulation, emulation support for this arcade game is very likely the last item on Githubthe to-do list.

===Potential roadblocks===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. End-users may wish to perform a preliminary dump of the required files from their PS4 using the  In recent years many [https://phiwww.nzplaystation.com/orbitalen-us/games/toolspc-games/dumperPlayStation 4 (Pro) exclusive titles are now being ported to PC] with [[#Enhancements|enhancements]], so similar to [[PlayStation_5_emulators#Emulation_issues|PlayStation 5]], [[Xbox One emulators#Emulation issues|Xbox One (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.
