 +
=== Unmount ===
 +
Takes an input [[#DeviceHandle]], no output.
 +
 
 +
=== OpenApplicationArea ===
 +
Takes an input [[#DeviceHandle]] and an input u32 [[#Access ID]], no output.
 +
 
 +
The amiibo must be already using its application area with the input access ID (the game must have already created savedata there). Result 0x10073 will be returned if no application area exists, result 0x13073 will be returned if the application area is currently used with a different access ID.
 +
 
 +
=== GetApplicationArea ===
 +
Takes an input [[#DeviceHandle]] and a type-0x6 output buffer, returns an output u32 size.
 +
 
 +
Reads the buffer data in the application area and returns the size read from the application area.
 +
 
 +
 
 +
The application area needs to be opened first.
 +
 
 +
=== SetApplicationArea ===
 +
Takes an input [[#DeviceHandle]] and a type-0x5 input buffer, no output.
 +
 
 +
Writes the buffer data in the application area.

 +
 
 +
=== GetDeviceState ===
 +
Takes an input [[#DeviceHandle]], returns an output u32 [[#DeviceState]].
 +

 +
Takes an input [[#DeviceHandle]], returns an output u32 NpadId.
 +
 
 +
=== GetApplicationAreaSize ===
 +
Takes an input [[#DeviceHandle]], returns an output u32 size.
 +
 
 +
Actually returns a hardcoded value of 0xD8.
