ResultNsDataNotFound	The specified NS data is not found. Might have been deleted with an auto-delete.
ResultInvalidNsDataGetHeadSize	The header size does not match the header type specified by the GetHeaderInfo function. Normally this doesn't occur, but it is possible that something abnormal occurred.
ResultStorageAccessPermission	You do not have permission to access storage. Cannot access the expanded save region. Re-confirm whether you have access rights.
ResultIpcNotSessionInitialized	Either a session had not been initialized or there were incompatible permissions. This Result is returned if this function is called before either the Initialize or the InitializePriviledged function is called. When using the BOSS library, always begin by calling either the Initialize or the InitializePriviledged function.
A value other than the above.	Unexpected error (see boss_Result.h for error details).
