Hacking Wii U image (WUD) compression tool

[Whovian NineThreeSixNine]

I personally just keep the Loadiine ready folders on my HDD. What might some advantages be to using this tool compared to just keeping the files handy?

can u merge wud files together?

 

[Mored1984]

Just drag & drop "WUX" OR "WUD" file to the desktop icon.

If there are any linux users out there, you can compile a native version if you make the following changes to the source:

replace all references to "_fseeki64" to "fseeko"
replace all references to "_ftelli64" to "ftello"
replace all references to "stricmp" to "strcasecmp"

Compile with "gcc main.cpp wud.cpp -o wiiu_compress"

Ummm, can i also compress my wii u game backups?

I looked through the source code... It looks like your tool is not bound to the WUD format specifically. It can be applied to any type of file. But the profit comes when the file has duplicate blocks of data of fixed size at fixed alignments. In your case it is 0x8000 block size. Which is also used in Wii isos.
I tried it with a Wii iso, and it's no help. I tried both, on unmodified iso, and on iso with the partitions decrypted. Looks like the unused space in Wii isos is filled with random garbage, which is not duplicated at all. The scrubbing tools just remove that garbage completly.
Pity. I hoped I could win some little extra space from compressing my Wii isos.

Hi, I was wondering if you can use this tool to put together split files of games (.part1, .part2,... rar files) and use it in cemu. For example, the game files obtained by extracting them with Uwizard. Can i put them back together with this tool? If not, could anybody tell me how i can do it?

It would be good if this tool could include the game decryption key inside the WUX container. That way one wouldn't have to keep the key in a separate file.

Hopefully this helps anyone in the community looking to shrink your roms like I once was. I've made a video tutorial showing how to use Exzaps WudCompress tool:

How to Compress .Wud Files to .Wux for CEMU 1.6.0 Wii U Emulator using WudCompress

It's just a coincidence. Probably not useful for loadiine due to the reason already stated by EclipseSin.

Can't compile it.... using Visual Studio 2017 Enterprise

 

[DarkGabbz]

Can't compile it.... and the exe file does not even work

Bumps thread.... and that name UH.

Well your gonna have to deal with it.

Hi there!
Do you guys know how to convert the Wii U tickets to WUD?
Any Programs that can help out?

 

[Pepitito0]

With this program can I convert loadiine rpx and rpl to wud

No, this tool simply converts WUD images into much smaller WUX images.

No. You can use nuspacker for that, but it's not recommended since downloading the NUS files directly is easier and results in a cleaner (closer to 1:1) dump that will also work without CFW as long as it's a retail game.

But it's illegal

I have a whole bunch of .app files, and title.cert, title.tik, and title.tmd. What do I do with those?

Sorry to bump, but how do you decompress it back to a .wud format?
Because I need to explore the game datas (need to find texts and models of Twilight Princess HD EUR), and DiscU can't extract WUX files, and I don't want redowload the whole 25GB wud file...
Thanks

EDIT : Sorry, I'm stupid... Simply drag'n'drop it again seems to work...
