 - [scePadOpenExt](../../core/libs/prx/libScePad/Export.cpp) (libScePad) - only special ports (type 2) are handled, and they return `DEVICE_NOT_CONNECTED` (0x80920007) because the host has no special controller; whether the console opens a handle and reports the device as disconnected later is unknown. 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

 - [sceAvPlayerAddSource](../../core/libs/prx/libSceAvPlayer/src/Source.cpp) (libSceAvPlayer) - requests up to 4 additional decode-ahead video framebuffers from the memory replacement beyond `num_output_video_framebuffers` when memory is available; the console's internal buffering behaviour is unknown
 - [sceTextToSpeech2Initialize](../../core/libs/prx/libSceTextToSpeech2/Export.cpp) (libSceTextToSpeech2) - the console's error for an unavailable speech engine is unknown; it returns the kernel's `EOPNOTSUPP` (0x8002002D). PPSA01317 passes a param that starts with 0x2000000 and only tests the result for non-zero; the other exports it imports are declared without parameters
 - [sceAgcDcbClearState](../../core/libs/prx/libSceAgc/DcbFlow/src/Control.cpp) (libSceAgc) - the (buffer, command) signature follows [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/main/src/SharpProspero/Interop/Agc/SceAgc.cs) and [OpenAGC](https://github.com/OpenAGC/OpenAGC/blob/main/src/game_compat.c), and the 2-dword CLEAR_STATE (0x12) packet is OpenAGC's; OpenAGC masks the command to 4 bits, here a command above 0xf throws, as the driver rejects that payload

 - [sceJpegEncEncode](../../core/libs/prx/libSceJpegEnc/Export.cpp) (libSceJpegEnc) - `restart_interval` follows SharpProspero's field doc (0 none, -1 every row of blocks, positive a block count); a positive value is taken as the JPEG DRI interval in MCUs and -1 as one restart per MCU row, which no reference confirms. Other negative values throw
 - [sceVoiceQoSInit](../../core/libs/prx/libSceVoiceQoS/Export.cpp) (libSceVoiceQoS) - `0x804E0905` for a second initialization comes from [prosper](https://github.com/mattias800/prosper)'s reading of the module and was not measured: on a PS5 a valid call blocks inside a homebrew payload, so it never returns there. The app type and the block are not used, as no endpoint is implemented

 - [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
