If a content is currently locked and the inputs match the locked content parameters, this decrements global counters for locked SD card and game card titles based on the media type. If an update title is available for the provided application, the appropriate counter will be decremented as well based on its media type. This also calls into some FS service functions in the range 0x870-0x878 with currently unknown purpose.

If a content is not locked or the provided parameters do not match, error C8A12405 will be returned.

This is used by the Instruction Manual applet, and is likely related to triggering SD/Game Card removal errors when ejecting the media the manual is stored on.
