libScePad technical debt

Unknown function info

• scePadUnknown_n3kSX62fgNo (libScePad, NID n3kSX62fgNo) - firmware 13.60 returned 0x80920005 before scePadInit and 0x809200ff after it in the #3177 probe; the tested call read or wrote no argument pointers. PPSA15645 calls the import after scePadOpen, but its return and side effects in that state are unknown. The NID name and signature are unknown, so the statuses are not named by presumed error meanings
• scePadSetAngularVelocityDeadbandState (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, 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 (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 (libScePad, NID iA-DdobUen8) - the name hashes to the imported NID; the (int handle, void* state) signature follows PS5VR (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 (libScePad) and sceVrTracker2ResetLocalCoordinate (libSceVrTracker2)
• scePadSetVibrationMode (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 names only 1 and 2). The stored mode has no other effect
• scePadIsRemoteController (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 (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
• scePadUnknown_zBsgF0q8DIM (libScePad, NID zBsgF0q8DIM) - PPSA03671 imports it and fails to load without it. The aerolib list has no name for the NID, and none of the pad names in SharpProspero, shadPS4 or OpenOrbis, nor the trigger effect, motion sensor, VR controller, HD and haptic names tried, hashes to it. It is declared without parameters and throws. The title's executable has an import stub for it but no call, jump or address reference to that stub, so the argument count and whether the result is used are unknown
• scePadUnknown_n3kSX62fgNo (libScePad, NID n3kSX62fgNo) - PPSA01530 and PPSA13356 import it and fail to load without it. The real name is unknown; it is declared without parameters and throws
