Roadmap

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 useful optimizations. (Nekotekina)
• Use compression to store compiled PPU modules. (Nekotekina)
• Fix some engine-specific rendering issues (kd-11)
• Improve the shader decompiler/recompiler (kd-11)
• Fix remaining problems with texture readback (write color buffers) (kd-11)

Medium term goals

• Improve SPU instruction accuracy for Fast Interpreter and ASMJIT
• Improve audio and video decoders for better speed and compatibility.
• Improve controller support. This includes emulated controllers (with mouse or keyboard) and real controllers as well.
• 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 solution structure, move and rename some files.
• Implement missing syscalls. Allow to LLE more system modules.
• Write automatic tests to minimize bugs.
• Enable hardware acceleration for decryption (AES-NI). (#2457)
• Implement config tristate in GUI for per-game configurations.
• Improvements to the shader generation and cache system
• Implement parametrized PPU Interpreter reusing current LLVM IR generator, remove original hard-coded PPU Interpreter and make LLVM mandatory. Add options regulating its accuracy detached from the base choice of the Interpreter or the Recompiler. The same extends to SPU.
• Remove obstacles for ASLR support. (Nekotekina)
• Rewrite signal handlers to improve reliability and support exceptions. (Nekotekina)

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

• Parse .eh_frame section in PPU analyser and use this information in LLVM recompiler.
• 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 BPIP for synchronization primitives.
• Cleanup the VS project files: reduce to two build types (Release and Debug), but both must use Release LLVM build. Debug build should include memory leak detection features.
