GetTitlePatchContentNcaPath

Takes a 0x16-type output buffer, an u8 type, and an u64 titleID.

The input titleID is used with the application-title table like various other cmds, anything not in that table can't be used with this.

Returns a string path for the specified type of patch content with this titleID, otherwise returns regular-application paths when update-title not installed. Returns an error when the specified type of content doesn't exist for this title. Starts with "@{SdCardContent,UserContent}://" and ends in ".nca".

For gamecard content, the output path is: "@GcS00000002:/<NcaId>.nca". NCA-type0 with gamecard returns 0 with an empty output string.

The output string is then used by the user-process with FS to mount the content.

GetFreeSpace

Takes an input media-id that must be 5.

Returns the u64 from Content_Manager_services#IContentStorage cmd22.

GetTotalSpace

Takes an input media-id that must be 5.

Returns the u64 from Content_Manager_services#IContentStorage cmd23.

GetTitlesInfo

Takes a type-6 output buffer and an u64.

Returns an array of title-info entries using the specified offset and size. No input titleID is passed to this.

GetTitleInfo1

Returns 0x10-byte entries using the specified titleID starting at the specified u32 entryindex. Can only return game titles. The second entry if any is the update-title usually. When the input entryindex is >= totalentries, this will return 0 with out_entrycount=0.

Entry structure:

Offset	Size	Description
0x0	0x1	u8 "type". Title type (String is from web-applet)
0x1	0x1	u8 "installedStorage" / StorageId (String is from web-applet)
0x2	0x1	Unknown. Non-zero with output from cmd 605, differs for app/update titles.
0x3	0x1	Padding
0x4	0x4	u32 Title-version
0x8	0x8	u64 titleID
