Web-applet loads the [[#FileSystemType]] (which must be '''ContentManual''') from u32_table[inparam].
Web-applet loads the [[#FileSystemProxyType]] (which must be '''Manual''') from u32_table[inparam].
Note: web-applet strings refer to both this cmd and [[#OpenFileSystemWithId]] as "MountContent", but official nn_sf_sync symbols use "OpenXX" names.

Takes a type-0x19 input buffer, an [[#FileSystemType]] and an u64 title-id. Returns an [[#IFileSystem]].
Takes a type-0x19 input buffer, an [[#FileSystemProxyType]] and an u64 title-id. Returns an [[#IFileSystem]].
The [[#IFileSystem]] must be '''ContentMeta''' if the NCA type is 0 (control).
The [[#IFileSystem]] must be '''Meta''' if the NCA type is 0.
The input buffer is the output string path from [[NS_Services#GetApplicationContentPath|GetApplicationContentPath]].

May return errors when attempting to access NCA-paths for an update-title with a gamecard, when the gamecard isn't inserted. May return error 0x7D402 in some cases with update-titles. Non-val2 in32 values with NCA-type1 are unusable, even for normal titles.

The official "MountApplicationPackage" func uses this with in64=0 and [[#FileSystemType]] '''ApplicationPackage'''.

After the [[#FileSystemType]] specific permissions are checked, it then gets the func retval for permissions-type 0x25 and func0.

When [[#FileSystemType]] is '''ContentMeta''', it uses in64=0xffffffffffffffff internally, otherwise it checks if in64 is set to 0xffffffffffffffff then throws an error if so. When the in64 used internally is not 0xffffffffffffffff, it's compared with the NCA [[NCM_services#ProgramId|ProgramId]], then an error is thrown on mismatch.
