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

Short term goals

  • Improve SPU/PPU LLVM recompiler compatibility, add more optimizations. (Nekotekina)
  • Implement parametrized PPU/SPU Interpreters reusing current LLVM IR generator, remove original hard-coded interpreters and make LLVM mandatory. Add options regulating its accuracy detached from the base choice of the Interpreter or the Recompiler. (Nekotekina)
  • Make journaling VFS layer or something that fits, properly implementing some missing features like case sensitivity. (Nekotekina)
  • Fix any remaining RSX regressions. (kd-11)
  • Fix surface cache leaks. (kd-11)
  • Merge RCB+RDB and WCB+WDB and make the new 'Read Buffers' option enabled by default. (kd-11)
  • Rework RSX <-> Cell synchronization framework to be more cohesive. (kd-11)

Medium term goals

  • Improve SPU instruction accuracy, investigate vectorized software FP implementation. Integrate as an option for SPU LLVM. Remove SPU Precise.
  • Improve controller support. This includes emulated controllers (with mouse or keyboard) and real controllers as well.
  • Improve solution structure, move and rename some files.
  • Implement missing syscalls. Allow to LLE more system modules.
  • Write automatic tests to minimize bugs.
  • Implement config tristate in GUI for per-game configurations.
  • Improvements to the shader generation and cache system
  • Swich to homebrew shared_ptr<> (Nekotekina)
  • Implement implicit event sending by invoking operator() with arguments for named_thread template, remove lf_queue and lf_fifo. (Nekotekina)
  • Get rid of RTTI (Nekotekina)
  • Improve internal profilers and statistic printers, at least ones in g_fxo. (Nekotekina)
  • Merge texture cache and surface cache into one structure and remove bloat (kd-11)

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.

Never-ending goals

  • Improve game compatibility by fixing bugs and missing functionality.
  • Continue to improve emulation speed and accuracy.
  • Improve performance and compatibility of all renderers.

For developers

  • 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).
