==Post-9.3.0-21==
==Post-9.3.0-21==
Commands for post-9.3.0-21 have been extracted by analyzing the amiibo Settings applet. Therefore this table may be missing commands.
Commands for post-9.3.0-21 have been extracted by analyzing the amiibo Settings applet. Therefore this table may be missing commands. Note that the function name is actually a nickname for easeness of reading, as original function names have been stripped off the binaries.


Command header is stored at [[Thread Local Storage|TLS]]+0x80. Input and output parameters, if any, are set at TLS+0x84 onwards. If the command specifies has a parameter named "pid", this value has to be set to 0x20, as the kernel will replace the next word ("pidPlaceholder" - which can be left uninitialized) with the process' real PID (see [[IPC_Command_Structure]]).
See [[IPC Command Structure]] for an explanation on how IPC communication works and how to use these functions.
