Contributing (TODO List)

  • Be patient!
    • Your contribution will gladly be reviewed, but free time is an expensive resource.
  • Discuss your future contribution with us before coding it!
    • Let's avoid duplicate work! Besides, the specification could be clarified this way.

QA / Portability

  • Port core thread to std::thread (current code is based on pthread, so low priority)
  • C11 aligned_alloc (mostly done, but doesn't work with asan and GCC4.9)
  • C++11 alignof/alignas syntax
  • Replace volatile/lock-free queue with real C++ atomic (mostly done, remains a couple of volatile in core)
  • C++11 auto port.
  • Clean header include. Investigate.
  • Address sanitizer (GCC or Clang) and other sanitizers.
  • Valgrind (not sure it can run PCSX2, maybe limit the scope to plugins)
  • Reformat the core/plugin to a constant style with clang-format (on-going by greg)


  • Check Linux chapter. Various improvements are actually cross-platform! ;)


You're welcome to the Linux contribution thread to have full details. Here is a handy list of features need implementation. Feel free to propose new ones.

House keeping and general compilation

  • Clean up warnings
    1. Same as GCC flags but without the need of complete test.
  • Clean up GCC flags
    1. Put default global flags in cmake/BuildParameters.cmake
  • Speed comparison Clang/GCC
  • Add missing/update copyright headers
  • LTO support
  • PGO support
  • clang-tidy (./ --clang-tidy)


  • Support XZ compressed ISOs


  • Implement DirectX features on OpenGL (and vice versa, if applicable)(video recording, port OSD from OGL, etc.)
  • Gameplay recording (so far, framebuffer is dumped every frame)

zzogl (plugin is kinds of dropped)

  • Reduce OpenGL requirement to 3.3 with OpenGL 4 extension
  • Use multibind
  • Fix EGL
  • Port GLSL to window
  • Drop old GLSL backend (and much later Nvidia CG)

Debian package

  • Needs a refresh to the latest standard
  • Clean Debian/copyright => debmake -k

Very long term features

Those features will require a lot of work, and an organized long-term effort.

  • PS2 ROM re-implementation (wrongly named HLE BIOS)
  • 64-bit port (32-bit yields better performance for the moment)
  • Android X86 port
  • Linux ARM port
  • Mac OS X support
You can’t perform that action at this time.
