Thanks a lot. I assumed thecoldboot CFW would skip the keys, but I gladly stand corrected. And I'll give those two utils a shot.
I've also seen youtubers use uwizard... Would this also suffice?
And as for dlc... would I be able to add these after installing the game to the hdd, or do I need to add them to the SD right after dumping?
Thanks!
sorry, nothing you said make sense. you probably mixed many things together.
I think you didn't understand enough how the console is working, and you'll need a little help.
First, about the keys.
You asked how to decypt WUD files, and doing that you need keys.
WUD is the format of a FULL disc copy, 24GB binary file (like the .iso format for CD or DVD).
the WUD file's content is encrypted, and to get its content you need the key to decrypt it
to your computer.
The WiiU does NOT use WUD file at all, does NOT need the key (because does NOT interact with WUD files at all, ever).
coldboot has nothing to do with needing or not needing keys.
the keys are needed on the extract/install step, not on the play/launch/boot step.
To get the game's data, you different choices:
1) extract the WUD to get the game files in "installable format" (.app files, imagine it as a passworded .rar or .zip file), like if it was downloaded from nintendo's network (eShop).
this is what you put on your SD card, and install the game with a program, which will unpack the .app files to your console in "file and folder" format.
2) extract the WUD to get the game files in "file and folder" format, like if it was "already installed to your console". You need both WUD keys and game keys.
getting the "file and folders" final format is not useful if you want to install the game to the console. It's used only by Loadiine (a game loader homebrew, old and deprecated, slow, not 100% working, no online possible).
Don't do that method.
1) and 2) are only in the case you dump or download the FULL WUD file format. but, don't get the full WUD at all ! unnecessary long, bandwidth wasting, space wasting, time wasting.
3) Dump your disc to .app format.
this is very easy. Launch the "disc to app" homebrew, it will extract the disc's game content to .app installable format.
if the game is 200MB, you'll get only 200MB on your SD card, not a full 24GB WUD file!
Being in .app format, you only need to use the package installer (WUPInstall) homebrew program to put the game into your console. (no keys involved !)
The "game key" is extracted from the disc itself. you don't need anything else than the disc.
4) get the game from WiiU Eshop Helper (not UWizard, which is old and not user friendly and not doing what you expect) or anything else doing the same thing (JNUStool, but not user friendly either), in .app format.
It's doing the same than 3), but it's taken from Nintendo's servers instead of your own disc.
You'll need some game keys (not WUD keys!) to generate a "ticket file".
the ticket contains the game key to decrypt the .app (it's the .app password) to extract the content in "file and folder" format to your WiiU.
5) About the DLC.
you ask if they go to HDD or SD. I don't know if you mix the devices.
the SD is used as intermediate device.
game data or DLC or game update in .app installable package format -> copy to SD -> .app install program -> WiiU memory or wiiU HDD.
once installed to the WiiU (memory or hdd) you don't need the .app files on your SD card anymore.
The game update and the DLC can be installed at anytime. they are located at a different location than the game.
they are not part of the game's file (best example : they are not part of the disc ! if you download the DLC officially, it will not write to the disc to add the DLC. the DLC is read from somewhere else, the same with the game update).
imagine it like this on your console or WiiU HDD:
disc or console or hdd/game/data/
console or hdd/game/update/
console or hdd/game/DLC/
you install each independently, in any order (you can install the game update or DLC first if you like).
6)
So, if you already have WUD files, you could either :
- use specific tools to extract its content (wud2app, DiscU), but you'll need the wud key (usually provided along the .wud file, or else you can't do anything with it). put the extracted .app files to your sd:/install/ folder.
if you don't have the wud key, you can delete your wud ! 24GB waste space.
or
- delete the wud anyway, and use either WiiU USB Helper program to get the same game from nintendo's servers or use disc2app to extract your disc again but in a .app instead of .wud file to your SD.
Conclusion : NEVER EVER rely on youtube tutorial.
they are OLD, DEPRECATED, BAD, and more important DANGEROUS !
NEVER GO TO YOUTUBE FOR INFORMATION !
(it's not personnal, it's just that 80-90% of users come from youtube and they all have problems. here, we really hate youtubers doing unproper guides. Never seen a good one. and of course old guide stay online which is very dangerous, videos can't be updated)
