 - [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

+- [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
 - [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
 - [sceVideoOutRegisterBuffers2](../../core/libs/prx/libSceVideoOut/src/Buffer.cpp) (libSceVideoOut) - buffer option 8 (STRICT_COLORIMETRY) is presented as option 0, with the stored values unchanged; what the console changes for it is unknown. Only options 0 and 8 are accepted
