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.

: 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. 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.

: A compatibility layer for Windows based on Kyty that's in early development.
==Emulation issues==
===Potential roadblocks===
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 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 [https://phi.nz/orbital/tools/dumper/ Orbital Dumper].
===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]].
