Hacking The different WiiU game's formats, and how to convert them

[admin]

thanks to CreeperMario for the chart.
I wanted to do this in a "current hacking situation" guide, but I post it here for the moment.

​

Legend:

• Blue boxes represent external storage locations, such as read-only discs and the console's storage.
• Red boxes represent files that exist in your computer/SD card
• Green boxes represent tools.

There are 3 origin (disc, eshop, or console)
and there are 3 format (wud, encrypted or decrypted)

Each format can be converted to another (except wud, it can't be generated back from encrypted content).


What you want for loadiine is the decrypted content, the files and folders format.
If you already have the Encrypted content, you can use a program to decrypt them.
I recommend Cdecrypt (command line windows) or JNUStool (Java), you will have to provide the encrypted title key to decrypt your encrypted content and the common key too (to decrypt the encrypted title key).

pick one of the tool you want here :

Disc dumper :
- Private device (WiikeyU?)
wudump
Disc2app dumps Disc and extract to encrypted content file format directly to SD or USB!

WUD compressors :
WiiU Image compression tool
JWUD Tool

Wud decrypters / Disc extractors : (Requires disc key + common key)
DiscU
UWizard
VGMToolbox
Wud2app
JWUD Tool

WUD decrypter+Content decrypter (Requires disc key [+ common key])
DiscU
JWUD Tool

Content decrypters (Requires title key [+ common key])
Cdecrypt (I didn't find the official v0.1 release url, website is offline, so I linked to v0.2)
JNUSTool
WiiU USB Helper (get NUS data and can forge fake ticket if none provided). Discontinued. a modded version can be found on reddit.

content encrypters (Requires common key)
NUS packer

NUS downloaders (Requires game's titleID [+ game's ticket])
NUSGrabber (no ticket used or generated), and a GUI
JNUSTool (no ticket used or generated)
UWizard (no ticket used or generated)
uTikDownloadHelper (use provided ticket to get NUS data). has a GUI.
FunkiiU (get NUS data and can forge fake ticket if none provided). has a GUI.

WiiU USB Helper (get NUS data and can forge fake ticket if none provided). Discontinued. a modded version can be found on reddit.
I probably forgot few of them here...

NUS downloader+Content decrypter (Requires game's titleID + titleKey + common key)
JNUSTool


Package installers:
WUP Installer (original from Crediar, not HBL compatible)
WUP Installer (HBL Version, from dimok), y mod, benoit934 mod, etc. (look on github for all the mods)
WUP Installer GX2


File dumpers
1) - For loadiine only:
dumpiine (Launched game rpx and rpl only)
Loadiine xml dumper (launched game incomplete cos.xml and app.xml, for loadiine only)
ddd (Launched Game virtual link to Code, content and meta folder)

These tools can only dump incomplete code folder (.rpx .rpl app.xml cos.xml) from the RAM which can result in some issues.
Additionally, ddd is dumping an incomplete virtual folder provided by the console which is a merged of both game+updates together, producing a bad dump of a game which can't be repacked to encrypted format.
In most cases the dumped files are fine for e.g. loadiine or Cemu, but when you try to repack them into encrypted NUS Files, they won't work on console.
The .xml's are incomplete (for example the complete permission section in the cos.xml is missing) and unloaded rpl's are NOT dumped at all (the preload.txt isn't dumped either). A NUS downloader can be used instead to get and decrypt the complete and original files which can be repacked.
2) - individual file dumpers:
Saviine Backup/restore the launched game's savegame only. requires a computer's server running at the same time.
SaveMii Backup/restore multiple savegames slots directly from the console (no server side required). Requires Mocha CFW. Savemii mod may works with CBHC.
3) - Full NAND Access:
WUP Server/Client
FSDumper
FT2SD
ftpiiU_everywhere

File writers:
WUP Server/Client
ftpiiU_everywhere
