* Proper handling of whence 3 & 4 * Accurate directory handling in open Directories can be opened, and can be created in open, these changes should handle that more accurately. * Mount /app0 as read only On real hardware, it's read only. * Proper directory flag handling. Even when directory is specified, it will still succeed to open non-directories. * Check for read only directories * Earlier ro check in posix_rmdir Hardware tests suggest these checks are in a different order * Clear temp folder on boot My tests rely on this, and some games do too. Two birds with one stone * Clang * Add missing DeleteHandle calls Whoops * Final flags adjustment in sceKernelOpen All my current tests are now hardware accurate. * Fix truncates Host ftruncate consistently fails on EINVAL, I'll need to test if this issue affected Windows too. * Windows hacks Windows is more limiting about how folders are opened and things like that. For now, pretend these calls didn't error. Also fixes compilation for Windows * Final touch-ups After expanding my test suite further, I found a couple more edge cases that needed addressing. Bloodborne audio is still broken, I'll look into that soon. * Remove hacky read-only behavior in posix_stat Bloodborne apparently uses the mode parameter here when querying it's audio files, and the mode we returned led to it disabling audio entirely. * Clang * Cleaner code * Combine fsync and sync flags According to FreeBSD docs, the "sync" flag is synonymous with the fsync flag, and is only included to meet the POSIX spec. * Log if any currently unhandled flags are encountered. These are rare and probably not too important, but log a warning when they're seen. * Update file_system.cpp * Update file_system.cpp * Clang * Revert truncate fix Using ftruncate works fine after moving the call to before the proper file opening code. * Truncate before open Open the file as read-write, then try truncating. This fixes read | truncate flag behavior on Windows. * Slightly adjust check for invalid flags Any open call with invalid flags should return EINVAL, regardless of other errors parameters might cause. |

shadPS4
General information
shadPS4 is an early PlayStation 4 emulator for Windows, Linux and macOS written in C++.
If you encounter problems or have doubts, do not hesitate to look at the Quickstart.
To verify that a game works, you can look at shadPS4 Game Compatibility.
To discuss shadPS4 development, suggest ideas or to ask for help, join our Discord server.
To get the latest news, go to our X (Twitter) or our website.
For those who'd like to donate to the project, we now have a Kofi page!
Status
Important
shadPS4 is early in development, don't expect a flawless experience.
Currently, the emulator can successfully run games like Bloodborne, Dark Souls Remastered, Red Dead Redemption and many other games.
Why
This project began as a fun project. Given our limited free time, it may take some time before shadPS4 can run more complex games, but we're committed to making small, regular updates.
Building
Important
If you want to use shadPS4 to play your games, you don't have to follow the build instructions, you can simply download the emulator from either the release tab or the action tab.
Windows
Check the build instructions for Windows.
Linux
Check the build instructions for Linux.
macOS
Check the build instructions for macOS.
Important
macOS users need at least macOS 15.4 to run shadPS4. Due to GPU issues there are currently heavy bugs on Intel Macs.
Debugging and reporting issues
For more information on how to test, debug and report issues with the emulator or games, read the Debugging documentation.
Keyboard and Mouse Mappings
Note
Some keyboards may also require you to hold the Fn key to use the F* keys. Mac users should use the Command key instead of Control, and need to use Command+F11 for full screen to avoid conflicting with system key bindings.
| Button | Function |
|---|---|
| F10 | FPS Counter |
| Ctrl+F10 | Video Debug Info |
| F11 | Fullscreen |
| F12 | Trigger RenderDoc Capture |
Note
Xbox and DualShock controllers work out of the box.

Keyboard and mouse inputs can be customized in the settings menu by clicking the Controller button, and further details and help on controls are also found there. Custom bindings are saved per-game. Inputs support up to three keys per binding, mouse buttons, mouse movement mapped to joystick input, and more.
Firmware files
shadPS4 can load some PlayStation 4 firmware files, these must be dumped from your legally owned PlayStation 4 console.
The following firmware modules are supported and must be placed in shadPS4's user/sys_modules folder.
| Modules | Modules | Modules | Modules |
|---|---|---|---|
| libSceCesCs.sprx | libSceFont.sprx | libSceFontFt.sprx | libSceFreeTypeOt.sprx |
| libSceJson.sprx | libSceJson2.sprx | libSceLibcInternal.sprx | libSceNgs2.sprx |
| libSceRtc.sprx | libSceUlt.sprx |
Caution
The above modules are required to run the games properly and must be extracted from your PlayStation 4.
We do not provide any information or support on how to do this.

Special Thanks
A few noteworthy teams/projects who've helped us along the way are:
-
Panda3DS: A multiplatform 3DS emulator from our co-author wheremyfoodat. They have been incredibly helpful in understanding and solving problems that came up from natively executing the x64 code of PS4 binaries
-
fpPS4: The fpPS4 team has assisted massively with understanding some of the more complex parts of the PS4 operating system and libraries, by helping with reverse engineering work and research.
-
yuzu: Our shader compiler has been designed with yuzu's Hades compiler as a blueprint. This allowed us to focus on the challenges of emulating a modern AMD GPU while having a high-quality optimizing shader compiler implementation as a base.
