ListApplicationRecord
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.
Application Record Format
Offset | Size | Description |
---|---|---|
0x0 | 0x8 | Title ID |
0x8 | 0x1 | Type? (Known values: 2=Installing?, 3=Gamecard?, 4=Installed?) |
0x9 | 0x1 | Unknown, usually 0x02 |
0xA | 0x6 | Unknown, usually zeros? |
0x10 | 0x1 | Unknown, seems to change between reboots and removing/reinserting gamecards |
0x11 | 0x7 | Unknown, usually zeros? |
LaunchApplication
Takes an input u64 titleID, returns an output u64 PID.
Launches an application title which is registered with NS.
GetApplicationContentPath
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: "@GcSXXXXXXXX:/<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.
GetTotalSpaceSize
Takes an input media-id that must be 5.
Returns the u64 from Content_Manager_services#IContentStorage cmd22.
GetFreeSpaceSize
Takes an input media-id that must be 5.
Returns the u64 from Content_Manager_services#IContentStorage cmd23.
GetApplicationDesiredLanguage
Takes an input u8 language-bitmask, returns an output u8 control.nacp langentry index.
User-processes generate the language-bitmask with the following for all 16 lang-entries: if(<either string in langentry[i] is non-empty>)bitmask |= 1<<i
ConvertLanguageCodeToApplicationLanguage
Takes an input u8 pointer for the resulting Id to be written to and a string represented as a u64 (i.e 0x53552D6E65 for 'en-US').
Returns 0 if an ID was successfully found, otherwise returns 0x25810.
GetApplicationControlData
Takes an input u8 flag, an u64 titleID, and a type-0x6 output buffer. Returns an output u32 for actual_size. Official user-processes use buffer size 0x24000. qlaunch only uses flag value 0x1.
Loads cached control.nacp to buf+0 and the cached icon to buf+0x4000. Returns an error if the buffer is too small.
ListApplicationContentMetaStatus
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 |
