Unimplemented core/libs/prx Symbols: Blocker PRX Resolution Matrix
When a game invokes a PS5 dynamic module function that is not yet implemented in AnyPS5's core/libs/prx subsystem, the runtime aborts with "what(): core/libs/prx: Unimplemented function <symbol_name>".
PlayStation 5 firmware exposes thousands of proprietary SCE functions across libkernel.sprx, libScePad.sprx, libSceGnmDriver.sprx, and libSceAudioOut.sprx. When a title reaches gameplay that invokes an unstubbed routine, execution terminates.
check_circleVerified Resolution Steps
Identify the Unimplemented Symbol Name
Look at the line immediately following what(): in your error log. It will specify the exact function name, such as sceKernelGetProcessTime or sceAudioOutSetVolume.
Check the Community Blocker Map & Upstream PRs
Search the symbol on GitHub boykopovar/AnyPS5 pull requests or AlxcBTW/anyps5-roadmap. Many functions already have pending PRs waiting for merge.
Apply Safe Stubbing or Pull Upstream Feature Branch
If the function is non-critical (like telemetry or trophies), you can compile from a community branch that stubs the symbol with a return code of 0 (SCE_OK).
help_outlineFrequently Asked Questions
What are PRX files in PlayStation 5 architecture?
PRX (PlayStation Relocatable eXecutable) files are Sony's equivalent of dynamic link libraries (.dll or .so). They contain dynamic symbols that the game loads at runtime.
How does AnyPS5 provide PRX functions?
AnyPS5 reimplements these libraries in C++ using host OS APIs (such as SDL2 for input, OpenAL/WASAPI for audio, and Vulkan for GCN/RDNA graphics).
