GPCS4 emulator

GPCS4 PS4 emulator for Windows – PC Desktop

Uploaded byBlowFlies


GPCS4 is a virtualization-based Play Station 4 Emulator for Windows, Linux, MacOS, iOS and Android that is under heavy development. It can only boot the firmware. Do not expect to play commercial games with it yet. It is also open-source and is a low-level emulator.

To run or develop GPCS4, a CPU supporting AVX instruction set as well as a graphics card supporting Vulkan are required.
Currently, only Windows build is supported.

Kernel ELFs generated from memory dumps will not work since writable segments might have been modified into a state where booting is not possible. Please generate proper binaries offline by decrypting ELF segments with SAMU on your actual console, not by dumping memory.


The emulator frame rate is very low, because there are currently no optimizations.
GPCS4 will recompile all the shaders, untiling all the textures and upload all the buffers every frame, making it less efficient.
Besides, there are still some problems in the game pad emulation.

Currently, GPCS4 need a path of main elf/bin as input parameter, and will redirect all app0 access to the folder where GPCS4.exe locate.
ie. /app0/ to E:\Code\GPCS4\Debug\

The experimental version is now aviable on the link button below.

The table lists the minimum system requirements for running GPCS4 emulator Windows


•Parsing PM4 command buffers and some other formats to recover the original Gnm calls

•Translate Gnm calls into vulkan calls

•Translate GCN bytecode into Spir-V bytecode

•Audio Basic implementation

•Gamepad Basic implementation

•TLS support is not complete yet, and possibly neither are some other initialization functions
