Hacking Crediar DiscU a tool that can extract Wii U images.

[Goku Junior]

to answer my own question - DiscU is buggy and can't handle certain .wud files.
the generic iso extractor of vgmtoolbox can be used to extract those images - WII U images require 'ckey.bin' in the vgmtoolbox\external\wiiu directory, and 'disckey.bin' in the same directory as the source .wud image file.

Wow Man, I was going to ask that, thanks for giving your solution !

Thanks for the info fossi, but still no joy here

hmm.. might be a bad/fake dump... which version do you have EU or US? if you post a md5 hash of your .wud I could compare it with my dump (when I get back home)

(and btw. for my EU SM3DW dump DiscU worked just fine.)

Try it with DiscU, sometimes one will work over the other.

I'm trying to have a play with this on Super Mario 3D World EU but getting error:

"Either the key is wrong or this is not a valid Wii U image (extract)!"

Can someone please verify these hashes for the .wad are correct?

these hashes match yours, so maybe one of your keys is wrong?

edit: using wrong ckey gives me same error as yours, so your common key (ckey.bin) must be faulty.

I tried DiscU first.

my Super Mario 3D World EU extracts fine with DiscU:

Spot on there. My disckey/titlekey matched your hash but my comman key was wrong. Re did the common key and all good

Thanks!

Okay, my hash for the WUD matches up with you guys but both my BIN key files are not matching up. I'm pretty sure I have the correct keys so I'm wondering if I'm formatting the files wrong or something - do they have to contain anything more than just the key string?

EDIT: I figured out I had to edit them in hex, so I did. However, the hashes are still wrong... argh.

 

[Wurztha]

When your pasting the keys into the .bin file press Ctrl & A to select everything before using Ctrl & V to paste it in.

 

[ByteBite]

Still no luck, I just don't know what I'm doing wrong. Been trying all sorts of hex/binary encoding programs but the hashes on the files never match up.

If I enter the keys in here the hashes both match up, so I know they're correct. I just don't know what I'm doing wrong with regards to translating them to a file.

 

[Wurztha]

Check out the section named "How do I set up the SD card to use Loadiine?" here:

sigh...once again:

if you have python installed:

python -c "import binascii; open('disckey.bin', 'wb').write(binascii.unhexlify('<pasteyourkeyhereinbetweenthequotes>'.replace(' ','')))"

works on mac,windows,linux with python installed. remove everything between the single quotes and paste the ascii key in. it will crap out the appropriate formatted .bin key file

Sorry, I thought I'd combed the various threads and didn't see anything on this. As you might be able to tell I'm not a programmer and have very limited understanding of how something like python functions. Anyway, thanks for the instructions, hopefully I won't have to spam this thread any more.

EDIT: Thanks, it works!

just copy the thing and paste it into the command line with your key in the text spot

Hi, I have WindWakerHDUSA.wud and DiscU.exe, how to use discU for extract the content?
I need to extract all musics

In the same folder:
ckey.bin
titlekey.bin
game.wud
DiscU.exe

and make a .bat with:
DiscU.exe titlekey.bin game.wud ckey.bin
pause

 

[Asia81]

yeah, i seen on trash, thanks anyway

my sizes varies also, but if it works I don't bother questioning it.

No. Just no..... This is horrible advice. You yourself shouldn't even follow this... People don't put random numbers in size fields.. They are there for a reason, verification...

I'm not sure what you're doing wrong honestly, as you haven't specified what you've done (besides discu, so i guess nothin?). Those look like update sizes, not game sizes. Your wud is messed up or you only downloaded part of it.
