# libScePad technical debt

### Unknown function info

- [scePadUnknown_n3kSX62fgNo](../../../core/libs/prx/libScePad/Export.cpp) (libScePad, NID `n3kSX62fgNo`) - the name is unknown, and the 0 returned after `scePadInit` is inferred, not measured. In the OS 10.01 system module the function takes no arguments, returns `0x80920005` before `scePadInit`, and otherwise sends a per-process value of 1 to ShellCore over Mbus, returning `0x809200ff` if that call fails and 0 if it succeeds, with or without an open handle. The #3177 probe measured `0x809200ff` in a process that is not a game; a game process is assumed to get 0. The ShellCore setting it changes is unknown and not modelled
- [scePadSetAngularVelocityDeadbandState](../../../core/libs/prx/libScePad/src/PadState.cpp) (libScePad) - with the deadband on, each angular velocity axis whose magnitude is below 0.017453292 rad/s (1 degree per second) reads as 0, before the orientation is integrated; it starts off. Threshold, per-axis test and default follow [duaLib](https://github.com/WujekFoliarz/duaLib/blob/03bad1bea2a36561b520846776f2a07ced6773e0/src/source/duaLib.cpp#L44), which reimplements the PC `libScePad.dll`; the console's threshold is not measured, and the deadband is kept per library rather than per handle since one pad handle exists
- [scePadOpen and scePadOpenExt](../../../core/libs/prx/libScePad/Export.cpp) (libScePad) - special ports (type 2) return `DEVICE_NOT_CONNECTED` (0x80920007) because the host has no special controller, and `scePadGetHandle` has no handle for them; whether the console opens a handle and reports the device as disconnected later is unknown. scePadOpenExt handles only special ports. PPSA01317 passes a 16-byte param that names the device by vendor and product id (`b7 0e 04 0e ...` for 0x0eb7:0x0e04) and skips the user on any negative result. Other port types throw
- [scePadVrControllerReadState](../../../core/libs/prx/libScePad/Export.cpp) (libScePad, NID `iA-DdobUen8`) - the name hashes to the imported NID; the `(int handle, void* state)` signature follows [PS5VR](https://github.com/theghostonline/PS5VR/blob/0e408909ce7a39891a2e06eee3438d07a09e11e3/app/src/app_vr.c#L326-L369) (PPSA99177), which passes a PS VR2 Sense controller handle from `scePadOpen` type 3 or 4 and a 0x68-byte state it reads as buttons at 0, stick bytes at 4 and a connected byte at 0x40. The title calls it only after `sceHmd2Initialize` succeeds, which it does not here, so every call throws; the state layout is otherwise unknown
- PPSA07411 PS VR2 imports declared without parameters, signatures unknown, added without an implementation because the title fails to load without them: [scePadVrControllerSetVibration, scePadVrControllerSetVibrationMode and scePadVrControllerReadCombinedState](../../../core/libs/prx/libScePad/Export.cpp) (libScePad) and [sceVrTracker2ResetLocalCoordinate](../../../core/libs/prx/libSceVrTracker2/Export.cpp) (libSceVrTracker2)
- [scePadSetVibrationMode](../../../core/libs/prx/libScePad/Export.cpp) (libScePad) - modes 1 to 3 and 5 are accepted and stored. On a PS5 (firmware 13.60) the call returns `0x80920005` before `scePadInit`, then rejects a mode of 0 or below with `INVALID_ARG` before it checks the handle, and returns `INVALID_HANDLE` for a bad handle with any higher mode; whether an open handle accepts modes above 3 was not measured, since the payload could not open a pad; 5 is accepted because PPSA25286 passes it on its open handle at start-up; the meanings of modes 3 and 5 are unknown (PPSA21480 calls it with 3 right after `scePadOpen` and aborts on failure; [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/main/src/SharpProspero/Interop/Pad/Pad.cs) names only 1 and 2). The stored mode has no other effect
- [scePadIsRemoteController](../../../core/libs/prx/libScePad/Export.cpp) (libScePad) - the name hashes to NID `fCWdlnmB1Ks`; the signature `(int handle, bool* remote)` comes from PPSA16064, which zeroes a byte, passes its address after `scePadGetControllerInformation` and ignores the result. The error codes follow the other pad calls. Controllers are local devices, so the answer is always false
- [scePadSetAngularVelocityBiasCorrectionState](../../../core/libs/prx/libScePad/Export.cpp) (libScePad) - inferred signature `(int handle, bool enabled)` follows `scePadSetTiltCorrectionState` and `scePadSetAngularVelocityDeadbandState`; an invalid handle returns `PAD_ERROR_INVALID_HANDLE`, disabling is a no-op, and enabling throws because bias correction is not modelled
- [scePadGetAccessibilityControllerState](../../../core/libs/prx/libScePad/Export.cpp) (libScePad) - the value a console reports for a DualSense is not measured; the emulated pad, which is not an Access controller, reports 0. The name hashes to NID `zBsgF0q8DIM`. In the OS 10.01 system module the `(int handle, uint32_t* state)` function returns `0x80920005` before `scePadInit`, then `INVALID_ARG` for a NULL `state` and `INVALID_HANDLE` for a bad handle, and otherwise asks the pad driver for a per-device value of the device behind the handle: 0 when no device is behind it, 1 when the driver has no answer, else the driver's value. What the values mean is unknown
