Description[edit]

This sends a raw NFC command to the tag. The inbuf/outbuf is the raw data to send/receive to/from the tag. With Amiibo tags the first byte in the inbuf is the command, followed by any parameters for the command if required.

outputsize value 0x800 will be used when it's >=0x800. An error will be returned if actual_output_size is larger than outputsize. This can only be used when initialized with type3, and when the TagState is 3.
