SetNfcEnabled
Takes an input bool, no output.
OutputTestWave
Takes an input bool and a #TestWaveType, no output.
ReadMifare
Takes an input #DeviceHandle, a type-0x6 output buffer containing an array of #MifareReadBlockData, a type-0x5 input buffer containing an array of #MifareReadBlockParameter, no output.
sdknso passes the same user-specified array-count for both buffers.
WriteMifare
Takes an input #DeviceHandle, a type-0x5 input buffer containing an array of #MifareWriteBlockParameter, no output.
SendCommandByPassThrough
Takes an input #DeviceHandle, a nn::TimeSpan, a type-0x6 output buffer, a type-0x5 input buffer, returns an output u32 out_size.
sdknso copies the output u32 into an u64. This is the actual size which was copied into the output buffer.
This allows using a raw NFC command. The input buffer contains the command data (id + params), and the output buffer contains the response.
KeepPassThroughSession
Takes an input #DeviceHandle, no output.
ReleasePassThroughSession
Takes an input #DeviceHandle, no output.

Initialize
Takes a PID, an AppletResourceUserId, an u64, a type-0x5 input buffer containing an array of #RequiredMcuVersionData, no output.
sdknso passes value 0 for the u64.
Internally this is mostly the same for each service, this differs depending on the service/cmd however.
Finalize
No input/output.
