Emulation {{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 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. Most projects will inevitably end up going the route of [[Wine]].

It currently offers the 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 homebrews 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. 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. ==Enhancements==<div style="overflow-x:auto;width:100%">{|class="wikitable" style="text-align:center;vertical-align:middle;width:100%"|- style="font-weight:bold;"! colspan=2 | Name!

Rendering games at 4K resolution is achieved through various rendering techniques and hardware features;[[Orbital]]:An openPlayStation 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-source lowbreed temporal and spatial anti-level emulator based on [[QEMU]]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, Orbital and then uses existing hypervisors like Intel HAXM algorithms to speed up performancefill in the non-rendered segments. A surprising amount of progress has been made for The checkerboarded screen can then be smoothed using an emulator anti-aliasing filter.

===PCSX4 & Fake Emulatorsfake emulators===Because most people don't understand how emulation really works, scammers try and take advantage of this by making [[Emulator scams|their own fake emulatoremulators]] for malicious purposes. The PS4 has seen its fair share of scams, the most notable and persistent of which being '''PCSX4'''. The scheme is very elaborate and clever, with a website designed to mimic [[RPCS3]]'s while using a similar naming scheme as [[PCSX-Reloaded|PCSX]] and [[PCSX2]] (both of which are legitimate). The site makes use of uses aggressive search engine optimization (SEO), meaning it's one of the top results for "PS4 emulator" on Google. There are three Two things that invalidate PCSX4's legitimacy:

* It is actually 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 a real an actual PS4, and modifying the GUI to display fake hardware usage stats alongside the game.
