 - [sceAgcDcbSetCfRegisterDirect, sceAgcDcbSetCfRegisterRangeDirect](../../core/libs/prx/libSceAgc/DcbState/src/Registers.cpp) (libSceAgc) - signatures follow [OpenAGC](https://github.com/OpenAGC/OpenAGC/blob/main/src/game_compat.c) and [SharpProspero](https://github.com/SvenGDK/SharpProspero/blob/main/src/SharpProspero/Interop/Agc/SceAgc.cs), which agree; the SET_CONFIG_REG (0x68) packet is OpenAGC's. The driver does not execute SET_CONFIG_REG, so a submitted packet throws
 - [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
 - PPSA23566 imports declared without parameters, signatures unknown: [sceAudioOut2UserGetSupportedAttributes](../../core/libs/prx/libSceAudioOut/src/AudioOut2System.cpp), [sceConvertKeycodeGetCharacterFromKeyboardData](../../core/libs/prx/libSceConvertKeycode/Export.cpp), [sceHttpSetCookieRecvCallback, sceHttpSetRedirectCallback, sceHttpsGetSslError, sceHttpsSetSslVersion](../../core/libs/prx/libSceHttp/Export.cpp), [sce::Json::MemAllocator::notifyError, sce::Json::Value::clear](../../core/libs/prx/libSceJson2/Export.cpp), [sceNetResolverAbort](../../core/libs/prx/libSceNet/Export.cpp), [sceNpCommerceDialogOpen2](../../core/libs/prx/libSceNpCommerce/Export.cpp), [sceNpEntitlementAccessGetPftFlag](../../core/libs/prx/libSceNpEntitlementAccess/Export.cpp), [sceProprietaryVoiceChatHelper{Initialize,Terminate,SetVoiceChatState,GetVoiceChatUsageState}](../../core/libs/prx/libSceProprietaryVoiceChatHelperPrx/Export.cpp), [sceVoice{GetResourceInfo,ResetPort,EnableChat,DisableChat}](../../core/libs/prx/libSceVoice/Export.cpp). Names from the shadPS4 aerolib NID list
+- PPSA01325 imports declared without parameters, signature unknown: [sceRudpActivate](../../core/libs/prx/libSceRudp/Export.cpp). Name from the shadPS4 aerolib NID list
+- [sceVoiceChatRequestCreateVoiceChatGroup, sceVoiceChatRequestJoinVoiceChatGroup](../../core/libs/prx/libSceVoiceChat/Export.cpp) (libSceVoiceChat) - assumed to take a request id and two pointers like the other `sceVoiceChatRequest*` calls; offline, every argument is ignored and `SIGNED_OUT` is returned, as for those
 - [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
