GPCS4

A Playstation 4 emulator just begin.
A project for fun, and technical research.

The only reason I start this project is learning 3D graphics, nothing serious.

Latest progress

First commercial game support, We are Doomed. Thanks for our developers.
It's not playable now, since the FPS is very low, because there's no optimizations at all currently.
GPCS4 will recompile all shaders, untiling all textures and upload all buffers every frame, making it less efficient.
Besides, there're still some problems on game pad emulation.
Will improve these things step by step.

First correct image rendered, although this is a 2D image demo, it's actuall rendered in 3D pipeline.
There're still some hardcode test code, but with more design, and most important, this time with our shader translator, no hand write shaders anymore.
Next I'll focus on Nier and improve the graphics implementation.

This is a privious running result of Nier:Automata, not correct though, I'll improve it.

Roadmap

• Graphics

  • 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.

• Hardware

  • Audio

    Just begin.

  • Gamepad

    Basic implementation.

• System

  • Dynamic linker

    TLS support is not complete yet, maybe some other initialization functions either.

  • System resource management, ie. Thread, virtual memory, synchronize object, file, clock.

    For functions which don not require system resource (ie. math functions),
    we'll use the system libraries directly.
    For others, we implement those one by one.

Build

To run or develop GPCS4, a CPU supporting AVX512 together with a graphics card supporting Vulkan are required.
Currently, only Windows build is supported.

Visual Studio 2017
LLVM/Clang
LLVM Compiler Toolchain Extension
LunarG Vulkan SDK
