ROADMAP

Structured roadmap for RPCS3 development

This is a non-exhaustive list of current goals made possible with the support of our generous patrons.

Short term goals

  • Implement PS3 firmware installer. Users only need to provide correct PS3UPDAT.PUP file and it will be automatically unpacked into /dev_flash.
  • Implement decryption on the fly. No more temporary files and additional steps. This affects, for example, EBOOT, SELF, SPRX, EDAT, and MSELF embedded files.
  • Implement SDAT decryption. No need to decrypt them manually. Currently some games may silently fail to boot.
  • Implement "Automatic LLE configuration" option (enabled by default). This will pick the most appropriate system modules (SPRX files) for a particular PS3 executable. It may be hard to pick them manually.
  • Cache compiled LLVM modules. You shouldn't recompile the same executable twice.
  • Parse .eh_frame section in PPU analyser and use this information in LLVM recompiler.
  • Configure Travis to automatically upload Linux binaries on GitHub.
  • Investigate early crashes on Linux. Avoid using executable dir completely. Create dev_hdd0 and other dirs.
  • Start to improve compatibility by fixing bugs and missing functionality.

Medium term goals

  • Enable hardware acceleration for decryption (AES-NI).
  • Improve audio and video decoders for better speed and compatibility.
  • Implement MSELF support without intermediate files. Currently it doesn't work at all. Depends on "decryption on the fly" task.
  • Improve controller support. This includes emulated controllers (with mouse or keyboard) and real controllers as well.
  • Enable Vulkan graphic renderer for Linux.
  • Add low-latency ASIO audio backend for Windows. With ASIO4ALL, it will work great on most modern hardware.
  • Add core audio backend for Linux.
  • Implement LLVM recompiler backend for SPU. This is actually a tremendous amount of work to make it useful, but it will also give the very important speed improvement (unless the SPU is not used at all).
  • Improve LLVM flexibility. For example, it could scan game folder for all executables and SPRX modules and recompile them ahead of time.
  • Implement PPU executable chain-loading.
  • Improve solution structure, move and rename some files.
  • Improve SPRX loading and unloading. This increases compatibility a lot.
  • Implement missing syscalls. Allow to LLE more system modules.
  • Write automatic tests to minimize bugs.
  • Implement savedata manager. Currently it doesn't have user interface.
  • GUI: Use Qt instead of wxWidgets.
  • Implement precise PPU interpreter.

Long term goals

  • Support booting from original game discs.
  • Implement user manager.
  • Support mic, camera, USB peripherals, etc.
  • Implement network functionality.
  • Implement every system module in the emulator. This will allow the emulator to work without the PS3 firmware.
  • Continue to improve speed, accuracy, and compatibility. This is a never-ending goal.

For developers

  • Fix undefined behaviour in bf_t (signed shift).
  • Implement MFC_DMA_TAG_CMD_STALL_NOTIFY_EVENT and other SPU events.
  • Return error_code from syscalls and functions to enable error reporting.
  • Improve embedded debugging tools (CPU, RSX, Kernel Explorer).
  • Implement simple thread pool (Thread.cpp)
  • Implement MFC thread for SPU DMA and other time-critical tasks.
  • Fetch memory attributes in sys_memory_get_page_attribute.
  • Implement BPIP for synchronization primitives.
