Before initialization `sceHmdGetFieldOfView` returns `NOT_INITIALIZED` for a non-null output, where shadPS4 checks the handle first and returns `HANDLE_INVALID`. The third argument of `sceHmdGetInertialSensorData` is unnamed there and taken as a count

[Device, field-of-view, assembly-error, distortion, sensor and DFU query signatures](../../../core/libs/prx/libSceHmd/Export.cpp) are recovered from native register use. Field of view and assembly errors each output four floats; device information occupies 64 bytes and distortion output spans 76 bytes. The remaining device/sensor/report field semantics and DFU status bit meanings are unresolved. Assembly confirms integer error returns where decompilation incorrectly inferred void. Protected bodies are unchanged.
[Reprojection initialization and display-buffer signatures](../../../core/libs/prx/libSceHmd/Export.cpp) are recovered: initialization takes a parameter pointer, 32-bit mode and null reserved pointer; display-buffer setup takes a VideoOut handle, two buffer indices and reserved pointer, while adding a buffer takes an index and reserved pointer. `StartMultilayer2` takes a parameter pointer and 32-bit mode. Parameter fields remain incomplete. Protected bodies are unchanged.
[Work-memory queries, capture start, separate-mode open and crash-report cancellation](../../../core/libs/prx/libSceHmd/Export.cpp) consume no arguments in the supplied native implementation. The mirroring aspect debug setter takes five 16-bit values followed by a byte mode; the individual scalar meanings remain unresolved. These argument lists are confirmed; protected bodies remain unimplemented.
