Frequently Asked Questions

PCSX4 is a beta PlayStation 4/5 emulator project based on hardware-assisted virtualization which allows you to play PS4 & PS5 games on your PC, macOS and Android. It requires your PS4 console to grab "playstation device identifier"(PDIX) to run original/OEM PS4 game disks. PS4 Emulator development was initially started with closed source in late 2014, but later shifted to semi-open source to boost development.

To avoid engaging in illegal activities and the misuse of source code, the developers of PCSX4 have chosen to make the emulator semi open-source. This means that while all components and plugins associated with PCSX4 are freely available and accessible as open source, the core executable remains closed source and is not publicly available.

PCSX4, has achieved a level of stability that allows it to successfully boot and run a significant portion of the Playstation 4 game library. However, it is important to note that the stability of the emulator can vary from game to game. This means that while some games may run flawlessly, others may experience performance issues or even fail to run entirely. The stability of individual games can also be influenced by updates and the introduction of new features to the PCSX4 emulator.

PCSX4 is actively developed, with updates typically released on a monthly/weekly basis. These updates may include performance improvements, bug fixes, compatibility enhancements, and occasionally new features. However, the frequency can vary based on the development progress and the nature of the changes being implemented.

Windows users need to install the .NET framework 3.5, VC++2015, and DirectX 11.1 platform update. Support for macOS is in beta due to limited Metal support.

A PlayStation device identifier (.pdix) is a file generated and extracted from a PS4 console with PS4 firmware ver. 4.55 or lower. It contains encrypted identifiers and SAMU key blobs that are unique for every device. PDIX must be linked to your PCSX4 account in order to play games.

To extract PDIX, navigate to https://PCSX4.com/extract-pdix on your PS4 web browser.

Yes, you can use a PS4 DualShock 4 controller with PCSX4. You can connect it via USB or Bluetooth. The emulator should automatically detect and configure the controller, but you may need to adjust some settings in controller settings.

PCSX4 includes an auto-update feature that checks for new versions when you start the application. You can also manually check for updates in the settings menu. Always ensure you're using the latest version for the best performance and compatibility.

PCSX4 performance can vary significantly depending on your hardware and the specific game being emulated. While some games may run at speeds comparable to a real PS4, others might run slower or experience occasional frame drops. High-end systems generally provide better performance. We're continuously working on optimizing the emulator to improve performance across a wide range of hardware configurations.

Yes, there are several ways to potentially improve emulation performance:

• Ensure your system meets the recommended requirements
• Update to the latest version of PCSX4
• Close other resource-intensive applications while using the emulator
• Experiment with different graphics settings within the emulator
• Make sure your GPU drivers are up to date

Some DirectX files may be missing in your system. Make sure you have DirectX 11.1 platform update KB2670838-x64 installed in your system.

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

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

Emulation is a complex process, and not all games will run perfectly. Performance and compatibility can vary depending on your hardware, the specific game, and the current state of the emulator. Make sure you're using the latest version of PCSX4 and that your system meets the recommended requirements. You can also try adjusting the emulator's settings to improve performance.

Currently, PCSX4 does not support online multiplayer functionality. The complexity of emulating the PS4's network infrastructure makes this a challenging feature to implement. Local multiplayer support works well with most games.

At present, PCSX4 does not have the capability to download official game updates or patches. You'll need to use the version of the game that's on your original disc. We recommend checking our compatibility list to see which version of a game works best with the current release of PCSX4.

No, you cannot run pirated games. PCSX4 is made in such a way that the game cache-image (GCI) is encrypted with a 256-bit header. We have a strict policy against piracy. We firmly believe in protecting the intellectual property rights of game developers and publishers. Please buy original games and support their developers.

At this moment, you can only use original PS4 discs with PCSX4. Dumping a digitally purchased game to .pkg from PS4 is not possible. This feature has not been added yet as it promotes piracy and people will misuse it.

PCSX4 accounts store unique machine-id and PDIX codes for each account. If our system detects any illegal activity, your account and IP-address will be permanently banned from our servers.
