@ -24,85 +24,122 @@ For WUD files, following additional operations are possible:
|
||||
* Compressing into .wux file format (from .wud and splitted .wud)
|
||||
* Verifing (comparing) to different wud images.
|
||||
|
||||
## How to use it
|
||||
At first you have to import the jnuslib.jar and the common key in the Settings class.
|
||||
## Maven
|
||||
```
|
||||
Settings.commonKey = Utils.StringToByteArray("12345678901234567890123456789012");

|

</dependency>
|
||||
```
|
||||
Then for each different source type, you need to use a an own NUSTitleLoader.
|
||||
|
||||
## Usage
|
||||
|
||||
|
||||
|
||||
### Gettings NUSTitles
|
||||
Gor each different source type, you need to use a an own NUSTitleLoader.
|
||||
|
||||
```
|
||||
//REMOTE
|
||||
byte[] commonKey = Utils.StringToByteArray("12345678901234567890123456789012");
|
||||
```
|
||||
#### Remote
|
||||
```
|
||||
// Loading a title with a public ticket
|
||||
NUSTitle nusRemote = NUSTitleLoaderRemote.loadNUSTitle(0x0005000E12345678L, commonKey);
|
||||
|
||||
//Loading a title with a public ticket
|
||||
NUSTitle nusRemote = NUSTitleLoaderRemote.loadNUSTitle(0x0005000E12345678L);
|
||||
|
||||
//Loading a title with an own ticket (key, titleid)
|
||||
Ticket ticket = Ticket.createTicket(Utils.StringToByteArray("12345678901234567890123456789012"), 0x0005000E12345678L);
|
||||
NUSTitle nusRemoteWithTicket = NUSTitleLoaderRemote.loadNUSTitle(0x0005000E12345678L);
|
||||
//LOCAL
|
||||
// Loading a title with an own ticket (key, titleid)
|
||||
Ticket ticket = Ticket.createTicket(Utils.StringToByteArray("12345678901234567890123456789012"), 0x0005000E12345678L, commonKey);
|
||||
NUSTitle nusRemoteWithTicket = NUSTitleLoaderRemote.loadNUSTitle(0x0005000E12345678L, commonKey);
|
||||
```
|
||||
|
||||
//With ticket on disk
|
||||
NUSTitle nusLocal = NUSTitleLoaderLocal.loadNUSTitle("path-to-app-files");
|
||||
|
||||
//Loading a title with an own ticket (key, titleid)
|
||||
Ticket ticket = Ticket.createTicket(Utils.StringToByteArray("12345678901234567890123456789012"), 0x0005000E12345678L);
|
||||
NUSTitle nusRemoteWithTicket = NUSTitleLoaderLocal.loadNUSTitle("path-to-app-files");
|
||||
#### Local
|
||||
```
|
||||
// With ticket on disk
|
||||
NUSTitle nusLocal = NUSTitleLoaderLocal.loadNUSTitle("path-to-app-files", commonKey);
|
||||
|
||||
//Loading a .woomy file
|
||||
NUSTitle nusWoomy = NUSTitleLoaderWoomy.loadNUSTitle("testfile.woomy");
|
||||
|
||||
//WUD
|
||||
//Loading a uncompressed WUD
|
||||
NUSTitle nusWUD = NUSTitleLoaderWUD.loadNUSTitle("game.wud");
|
||||
//Loading a compressed WUD (WUX)
|
||||
NUSTitle nusWUX = NUSTitleLoaderWUD.loadNUSTitle("game.wux");
|

//Loading a uncompressed splitted WUD (2gb parts)
|

NUSTitle nusWUDSplitted = NUSTitleLoaderWUD.loadNUSTitle("game_part1.wud");
|
||||
// Loading a title with an own ticket (key, titleid)
|
||||
Ticket ticket = Ticket.createTicket(Utils.StringToByteArray("12345678901234567890123456789012"), 0x0005000E12345678L, commonKey);
|

// Loading a .woomy file
|
||||
NUSTitle nusWoomy = NUSTitleLoaderWoomy.loadNUSTitle("testfile.woomy");
|
||||
```
|
||||
#### WUD/WUX
|
||||
```
|
||||
// WUD
|
||||
|
||||
// Loading a uncompressed WUD
|
||||
WUDInfo wiWUD = WUDLoader.load("game.wud"); // needs a game.key next to the .wud
|
||||
// Loading a compressed WUD (WUX)
|
||||
WUDInfo wiWUX = WUDLoader.load("game.wux"); // needs a game.key next to the .wux
|
||||
// Loading a uncompressed splitted WUD (2gb parts)
|
||||
WUDInfo wiWUDSplitted = WUDLoader.load("game_part1.wud"); // needs a game.key next to the .wud
|
||||
|
||||
// Loading providing the disc key
|
||||
WUDInfo wiWUXWithDisc = WUDLoader.load("game.wux", Utils.StringToByteArray("12345678901234567890123456789012")); // needs a game.key next to the .wux
|
||||
// Loading a wud with no titley key (kiosk)
|
||||
WUDInfo wiKiosk = WUDLoader.loadDev("game.wux");
|
||||
|
||||
// Get NUSTitles from WUDInfo
|
||||
List<NUSTitle> titlesFromWUD = WUDLoader.getGamePartionsAsNUSTitles(wudInfo, commonKey);
|
||||
```
|
||||
|
||||
Once the title is loaded, you can use one of the services to extract and decrypt files.
|
||||
Here are some of the operations you can do. Look at the code for the full list of methods.
|
||||
|
||||
### Decryption:
|
||||
|
||||
For the decryption you can use a FSTDataProvider in combinations with a FSTEntry. Example:
|
||||
```
|
||||
DecryptionService decrypt = DecryptionService.getInstance(title);
|
||||
// Get a FSTDataProvider from NUSTitle
|
||||
FSTDataProvider fstdataprovider = new FSTDataProviderNUSTitle(nustitle);
|
||||
|
||||
//Decrypt the whole FST into a folder called "DecryptedTitle"
|
||||
decrypt.decryptAllFSTEntriesTo("DecryptedTitle");
|
||||
// When loading from a WUD, you can get the data of all partitions via
|
||||
List<FSTDataProvider> partitionsFromWUD = WUDLoader.getPartitonsAsFSTDataProvider(wudInfo, commonKey);
|
||||
// the includes all non-nustitles like the SI or UP partitions.
|
||||
|
||||
//Decrypt the code folder into a folder called "code_folder"
|
||||
decrypt.decryptFSTEntriesTo("/code/.*", code_folder);
|
||||
FSTEntry fstRoot = fstdataprovider.getRoot();
|
||||
|
||||
//Decrypt all .js files into a folder called "js_files"
|
||||
decrypt.decryptFSTEntriesTo(".*.js", js_files);
|
||||
FSTEntry appxml = FSTUtils.getFSTEntriesByRegEx(fstdataprovider.getRoot(), ".*app.xml").get(0); // get all .rpx files
|
||||
|
||||
// Get data as byte array
|
||||
byte[] appxmlData = fstdataprovider.readFile(appxml);
|
||||
// Get 1024 bytes from entry appxml from offset 0
|
||||
byte[] appxmlChunk = fstdataprovider.readFile(appxml, 0, 1024);
|
||||
|
||||
//Decrypt all .app files into a folder called "decrypted_contents"
|
||||
decrypt.decryptAllPlainContents("decrypted_contents");
|
||||
// Get data as input stream
|
||||
InputStream appxmlStream = fstdataprovider.readFileAsStream(appxml);
|
||||
// Get 1024 bytes from entry appxml from offset 0 as input stream
|
||||
InputStream appxmlStream = fstdataprovider.readFileAsStream(appxml, 0, 1024);
|
||||
|
||||
|
||||
//Use decrypting inputstream. Data will be only loaded/decrypted on demand.
|
||||
|
||||
//Display the app.xml as hex dump
|
||||
FSTEntry appXMLEntry = title.getFSTEntryByFullPath("code/app.xml");
|
||||
decrypt.getDecryptedOutputAsInputStream(appXMLEntry);
|
||||
//Lets just print the app.xml as hex data
|
||||
int BUFFER_SIZE = 0x40;
|
||||
byte[] buffer = new byte[BUFFER_SIZE];
|
||||
int i = 0;
|
||||
while(in.read(buffer) > 0){
|
||||
System.out.println(String.format("0x%04X: ", (i++ * BUFFER_SIZE)) + Utils.ByteArrayToString(buffer));
|
||||
// Save data to output stream
|
||||
FileOutputStream appxmlOut = new FileOutputStream(new File(appxml.getFilename()));
|
||||
if (fstdataprovider.readFileToStream(appxmlOut, appxml)) {
|
||||
System.out.println("Okay.");
|
||||
}
|
||||
in.close();
|
||||
[...]
|
||||
```
|
||||
|
||||
Some wrapper functions can be found in the DecryptionService:
|
||||
```
|
||||
FSTDataProvider fstdataprovider = new FSTDataProviderNUSTitle(nustitle);
|
||||
DecryptionService decrypt = DecryptionService.getInstance(fstdataprovider);
|
||||
|
||||
// Decrypt the whole FST into a folder called "DecryptedTitle" and skip existing
|
||||
decrypt.decryptAllFSTEntriesTo("DecryptedTitle", true);
|
||||
|
||||
// Decrypt the code folder into a folder called "code_folder" and skip existing
|
||||
decrypt.decryptFSTEntriesTo("/code/.*", "code_folder", true);
|
||||
```
|
||||
|
||||
### Extraction:
|
||||
```
|
||||
//Get the Service for the NUSTitle
|
||||
ExtractionService extract = ExtractionService.getInstance(title);
|
||||
ExtractionService extract = ExtractionService.getInstance(nusTitle);
|
||||
|
||||

||||

} else {

### Cleanup:
|
||||
Call the method cleanup() for a NUSTitle to cleanup/close all opened ressources.
