The '''PlayStation 4''' (PS4) is an eighth-generation console produced by Sony Computer Entertainment on November 15, 2013, and retailed for {{Inflation|USD|399.99|2013}}. It is the first PlayStation console to use the [[wikipedia:x86|x86]] architecture, a semi-custom 8-core AMD Jaguar CPU at 1.6 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 tasks.
The '''PlayStation 4 Pro''' (codenamed Neo, model number CUH-7000) console produced by Sony Computer Entertainment on November 10, 2016, and retailed for {{Inflation|USD|399.99|2016}}. It is an upgraded version of the PlayStation 4 with improved hardware to enable 4K rendering and improved [[#Hardware_features_and_peripherals|PlayStation VR]] performance, including an upgraded GPU with 4.198 teraflops of processing power and hardware support for checkerboard rendering, and a higher CPU clock. As with PS4 "Slim", this model also features support for USB 3.1, Bluetooth 4.0 and 5.0 GHz Wi-Fi. The PS4 Pro also includes 1 GB of DDR3 memory that is used to swap out non-gaming applications that run in the background, allowing games to utilize an additional 512 MB of the console's GDDR5 memory. Although capable of streaming 4K video, '''the PS4 Pro does not support Ultra HD Blu-ray'''. Games marketed by Sony as PS4 Pro Enhanced have specific optimizations when played on this model, such as 4K resolution graphics and/or higher performance. 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.[https://en.wikipedia.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.

:; [[Kyty]]:: A compatibility layer for the PS4 and PS5 made by InoriRus, the creator of Short Waves. It's in the early stages of development. It can boot commercial games such as ''Blackhole'', ''Worms W.M.D'', and some PS5 homebrews with 0.2.0. This is also the first-ever PlayStation 4 emulator with a GUI, and like GPCS4, the emulator is Windows-exclusive.

It can show the logos in [https://en.wikipedia.org/wiki/Nier:_Automata ''Nier: Automata''] and ran its first commercial games, ''We Are Doomed'' and [https://en.wikipedia.org/wiki/Sonic_Mania ''Sonic Mania''], in February 2020. It can only run homebrew tests as of June 2022. It Furthermore, it appears to be only a side project to test 3D graphics and may or may not become anything serious, but this is unknown as the project's development has halted. As of June 2022, GPCS4 is now a one-person project.
:; PS4Delta:: A compatibility layer for the PlayStation 4. It's unable to boot any commercial games and appears to do almost nothing than load some firmware modules. Development has stopped, and the project is archived on GitHub. ;Native:; PlayStation 5:: The 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.

===PlayStation Dynamic Menu and apps===
:[https://www.psdevwiki.com/ps4/Interface psdevwiki: PlayStation Dynamic Menu]
:[[Wikipedia:List_of_PlayStation_applications|Wikipedia: List of PlayStation applications]]
PlayStation Dynamuc Menu is a graphical user interface developed by Sony Computer Entertainment. You can launch various applications from this interface as well.
 
*No emulator supports this at the moment, although there are various reports on RPCSX discord channel that RPCSX booting VSH [https://discord.com/channels/252023769500090368/1133492361180233728/1173714720558166108 without any graphics] or [https://discord.com/channels/252023769500090368/1124815779230122096/1193992662743781396 2d elements with safe mode].
 
===Trophies===
:[https://psnprofiles.com/trophies?platform=ps4 PSNProfiles: PlayStation 4 Trophies]
Trophies are PlayStation Network awards presented to players for completing specific tasks in a game. The feature is present in most PlayStation 3 games, and all PlayStation Vita, PlayStation 4 and PlayStation 5 games.[https://playstation.fandom.com/wiki/Trophies] Trophies shouldn't be confused with [[#Enhancements|RetroAchievements]].
 
===Blu-ray drive===
PlayStation 4 and PlayStation 5 consoles supports Blu-ray Disc Video and DVD-Video. However it does not have the capability to play VCDs or <abbr title="Needs 'Ultra HD Blu-ray drive'">4K Ultra HD</abbr>, additionally, the VCD format is not supported by the consoles system software.

===PS4 Pro Enhanced games===
:[[Wikipedia:Category:PlayStation_4_Pro_enhanced_games|PlayStation 4 Pro enhanced games list]]
Games marketed by Sony as PS4 Pro Enhanced have specific optimizations when played on this model, such as 4K resolution graphics and/or higher performance. 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]

==Emulation issues==
===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. 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]], 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. 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.
===PCSX4 & fake emulators===
* The obstruction of the download behind endless surveys. Emulator development nowadays gets its funding from [[Emulators on Patreon|Patreon]] or Google Play.
* It is fairly easy to fake a PS4 (and even [[PlayStation 5|PS5]]) emulator by taking the open-source [https://git.sr.ht/~thestr4ng3r/chiaki Chiaki] Remote Play client, which works by streaming games from an actual PS4, and modifying the GUI to display fake hardware usage stats alongside the game. If its claims of running any PS4 game in 4K at 60FPS with little to no issues were true, there would certainly be news articles about it, just like there were for [[Cemu]].
