 {{for|emulators that run on PlayStation 4|Emulators on PS4}}  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 has is the first PlayStation console to use the [[wikipedia:x86|x86]] architecture, a semi-custom 8-core AMD x86-64 Jaguar CPU at 1.6 GHz, whereas one . One of the cores is utilised utilized separately only for low-power, background tasks. The CPU is shared shares its place on an APU chip with alongside a semi-custom AMD GCN Radeon GPU. They are supported by 8 GB GBs of GDDR5 RAM at 2.75 GHz, while 256 MB MBs of DDR3 RAM is used only for background tasks. Notably The '''PlayStation 4 Pro''' (codenamed Neo, it 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 first PlayStation console 4 with improved hardware to use the enable 4K rendering and improved [[wikipedia:x86#Hardware_features_and_peripherals|x86PlayStation VR]] architectureperformance, 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, making it easier allowing games to program for than 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 3 emulators|PlayStation 3]] while also having 4(Pro) will prove to be a monumental task owing to the complexity of x86_64 and the same architecture as PCsRadeon-based GPU.

==Overview==;Compatibility layers===Potential Roadblocks===:; fpPS4 Due to the PS4's 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 writing this, little to no documentation on the GPU (a modified Radeon 7970M : A PlayStation 4 compatibility layer made with disabled stream processors) used in the PS4's APU, and it will require a complete re-implementation by emulator developersFree Pascal. End-users may wish to preform a preliminary dump of the required files from their PS4 using It currently offers the [https://phi.nz/orbital/tools/dumper/ Orbital Dumper]best game compatibility.

:; Obliteration:: A compatibility layer for Windows based on Kyty that's in early development. Promising work has been done on this emulator, however it's unable to boot any commercial games. :; shadPS4:: An PS4 compatibility layer. It can only run simple 2D games at the moment. :; psOff:: Yet another compatibility layer. Developer solely focused on the rendering part and recently started to implement the system functions to run some binaries. It renders decently fast, the planned changes will make it almost perfect. It currently doesn't support: multiple command buffer submits, for loops in shader, missing opcodes.[https://github.com/SysRay/psOff_public?tab=readme-ov-file#description] It can currently run Worms W.M.D., Sonic Mania, Tomb Raider I-III Remastered, Undertale, Deltarune and Blackhole with 60 FPS. Red Dead Redemption shows its legal warnings before crashing. :; [[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. :; [[GPCS4]]:: A compatibility layer for the PlayStation 4. 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. 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.

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. *See [[Home_Media_Player#Emulators|this dedicated page]] for more information about home media playback support for emulation softwares.*See [[Ripping_games]].*Also see [https://www.psdevwiki.com/ps4/Backwards_Compatibility#multimedia psdevwiki: multimedia support] ===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] ==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 the to-do list. ==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]], 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 Emulatorsfake emulators===Because most people don't understand how emulation really works, people scammers try and take advantage of this by making [[Emulator scams|their own fake emulatoremulators]] for malicious purposes. The PS4 has been the subject seen its fair share of a lot of these scams mainly since it was the "newest" console at the time, the most notable one however was one called and persistent of which being '''PCSX4'''. ItThe scheme is very elaborate and clever, with a website designed to mimic [[RPCS3]]'s while using a really clever cover up, the name is similar to "naming scheme as [[PCSX-Reloaded|PCSX" ]] and "[[PCSX2" ]] (both of which are well-known PlayStation emulatorslegitimate) and has a nice looking website similar to other recent emulation projects with the same elements. What makes it worse is The site uses aggressive search engine optimization (SEO), meaning it's one of the first top results on Google when searching for "PS4 emulator"on Google. Two things invalidate PCSX4's legitimacy: * 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.
