CreateAppletResource

Takes a PID and an u64 AppletResourceUserId. Returns an #IAppletResource.

SetSupportedNpadStyleSet

Takes an u32 #NpadStyleTag.

GetSupportedNpadStyleSet

Returns an u32 #NpadStyleTag.

The input buffer contains an array of u32 #NpadIdType.

AcquireNpadStyleSetUpdateEventHandle

Takes an input u32, an u64 AppletResourceUserId, and an u64. Returns an output event handle, autoclear for this is user-specified.

The value for the last u64 doesn't seem to matter (?): official sw sets this to the address of the structure used for storing the event which is initialized after using this cmd.

SetNpadJoyAssignmentModeSingleByDefault

Takes a PID-descriptor, an u32, and an AppletResourceUserId. No output.

SetNpadJoyAssignmentModeSingle

Takes a PID-descriptor, an u32, AppletResourceUserId, and s64 NpadJoyDeviceType. No output.
