What is PCSX4?

PCSX4 is a beta PlayStation 4 emulator project based on hardware-assisted virtualization which allows you to play PS4 games on your PC & macOS. It requires your PS4 console to grab “play-station device identifier” (PDIX) and original PS4 games. Follow this quick start guide for more info.

Why is PCSX4 semi open source?

To avoid illegal activities and misuse of source code, PCSX4 is made semi open source. All components & plugins of PCSX4 are open source except the core executable.

System and hardware requirements

Which operating systems are supported?

Only 64bit Windows 7, 8.1, 10 & macOS 10.13.6 or later is supported. Windows users need to install .net framework 3.5, VC++2015 & DirectX 11.  Support for macOS is in beta due to limited Metal support.

Which CPU's are supported?

PCSX4 is optimized to use up to 8 cores of a processor but requires at least 4 core processor with SSE-4.2 and AVX.

Intel: Core-i5 3xxx and later is supported.

AMD: FX-41xx and later is supported.

CPU performance and stability with PCSX4 differ drastically and it is difficult to tell which processor works perfectly. Some mobile-based i5 and i7 processors may cause performance glitches due to lower clock rates.

Which GPU's are supported?

PCSX4 requires a GPU to support at least Direct 3D 11.1 and Pixel shader model 5.0.

Nvidia: GeForce GTX 670 or higher is required.

AMD: AMD Radeon 7870 or higher is required.

To run every game smoothly @60FPS with 1080p resolution, GeForce GTX 980 or Radeon RX 580 can be recommended. PCSX4 does support 4K resolution but it is very difficult to reach 60FPS even with dual high-end GPU’s.

How much memory (RAM) is required?

5GB is a minimum requirement for PCSX4 but 8GB or more is recommended. 

Which macOS devices are supported?
  • MacBook Pro: late-2018 or newer with dedicated GPU.
  • Mac Pro: late-2015 or newer
  • iMac Pro: late-2018 or newer
  • iMac: mid-2018 or newer


What is PDIX?

A PlayStation device identifier (.pdix) is a file generated and extracted from a PS4 console which contains encrypted identifiers info and SAMU key blobs which is unique for every device. Please note that no personal information is used while extracting the file, PDIX must be linked to your PCSX5 account in order to play games.

How to extract PDIX?

To extract PDIX, navigate to https://pcsx4emulator.com/extract-pdix on your PS4 web browser.


"The application was unable to start correctly (0xc000007b)"

Some DirectX files may be missing in your system, make sure you have DirectX 11.1 installed in your system.

"This program can't start because MSVCP140.dll is missing"

PCSX4 uses VisualC++2015 for compiling, make sure you have Visual C++2010 redistributable (64-bit) installed in your system.

"This application has failed to start because XINPUT1_3.dll was not found"

PCSX4 requires the latest DirectX runtime, install it to fix this error.

Error 21: unable to execute "pdix-sniffer" binary from tty/USB0

Make sure you have “pdix-sniffer” file in the root of your flash drive. Your flash drive must be formatted with FAT32 format.


Can I run pirated games?

No, you’re not allowed to use pirated games. We have a strict policy about piracy, please buy original games and support their developers.

Can I dump digitally bought games?

At this moment you can only use original PS4 discs with PCSX4. Dumping a digitally purchased game from your console is possible, but this feature has not been added yet as people will misuse it.

Why my PCSX4 account is banned?

PCSX4 account stores unique Machine-id and PDIX for each account, if our system detects any illegal activity, your account and IP-address will be permanently banned from our servers.
