A PlayStation 4 emulator which was just started.
A project done for fun, and for technical research.
The only reason I have started this project is for learning 3D graphics.
It's not intended to become a serious application.
- Support simple compute shader, compute ring, cube maps.
- Use Direct Input to emulate pad.
First commercial game support, We are Doomed. Thanks to our developers.
It's not playable now, since the FPS 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.
We will try to resolve these issues incrementally.
-
- Gnm reverse engineering
Parsing PM4 command buffers and some other formats to recover the original Gnm calls.
Still a lot of work. - Vulkan backend
Translate Gnm calls into vulkan calls. Far from complete.
- Shader recompiler
Translate GCN bytecode into Spir-V bytecode. Far from complete.
- Gnm reverse engineering
-
- Audio
Basic implementation.
- Gamepad
Basic implementation.
- Audio

- Dynamic linker
TLS support is not complete yet, and possibly neither are some other initialization functions.
- System resource management, ie. Thread, virtual memory, synchronize object, file, clock.
For functions which do not require system resource (e.g: math functions),
we'll use the system libraries directly.
For others, we will try to implement them, one by one.
- Dynamic linker

To run or develop GPCS4, a CPU supporting AVX instruction set as well as a graphics card supporting Vulkan 1.3 are required.
Currently, only Windows build is supported.
