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

[Mikep90]

When you used the correct Wii U common key (confirm by looking into the logs) and the 01_sigpatches.rpx file is there it should work... In case it still doesn't please show us NUS Packers logs (make sure to censor the Wii U common key inside before, else this is a break of the forums rules).

well i guess i didn't have it setup correctly than. its working now

I've retired now, but back in the day, I used an little app called NUSPACKER, click HERE for more info.

Those are intended for CEMU, you can't install em directly to your Wii U.

Use NUSspli to download + install games to your Wii U instead.

NUSspli is slow...

NUSspli is slow...

Then use a program on PC. Is much faster.

That would be a fault of the Wii U itself, not NUSspli. Only way to boost speeds is to use a LAN adapter since the Wii U's network hardware is shit.

If you'd like faster speeds, then I recommend a tool like WiiUDownloader for a GUI or FunKiiU if you don't mind a CLI tool. Just download the title and copy the files to SD:/install/<folder_name> and install using either WUP Installer or NUSspli.

I've noticed a few games are no longer obtainable as NUS, but preserved as WUA. Is there still no way of converting them to run on actual Wii U hardware?

All games are available as NUS/WUP.

Is there still no way of converting them

https://github.com/Exzap/ZArchive/releases/latest - This gives you "raw game data". See the second answer in this thread for how to convert this to whatever you want then.
Or, well, just download the game in the correct format. A few buzzwords for you:
- Wii U Downloader
- NUSspli
- MarioCube Google Drive

No-intro decided to archive the CDN content as regular *.h3 and a single tmd.* file.

This means no title.cert, title.tik and title.tmd.

Does this means those are all decrypted content, correct?
And you would need a tool and also the keys to pack it again to run into original hardware?

 

[V10lator]

@veggav No, it's still encrypted. The tmd file is the title.tmd and .tik and .cert are missing. The .app files are just missing their file extensions.

What you see is basically the format the files are stored on the NUS/CDN when you're not authenticated (that's why title.key is missing. title.cert the console is able to create on the fly from the .tik and .tmd files).

NUSspli should be able to install this directly through (silently calculating the missing key, temorary renaming files and creating a (also temporary) fake tickt used for installation).

 

[veggav]

Thanks, I figured NUSspli would only be able to install from NUS and not from an SD card.

Appreciate the info.

Everybody (and I mean EVERYBODY, even expert Wii-U tool developers) says that a WUA file can't be converted back to extracted content (loadiine) because some metadata or encryption is lost during the conversion to WUA or something like that, however, and thanks to your humble comment I discovered that ZArchive in fact it CAN extract WUA content back to loadiine, and it works perfect in CEMU.

It's as easy as dragging the WUA file to zarchive.exe, or using it via command-line.

How is it possible that EVERYONE (except you at least, and of course probably few more people around there) ignores this information and creates misinformation by constantly stating that a WUA file cannot be extracted?. I have read dozens and dozens of comments in this forum from users asking how to decompress a WUA file (because I also have that need, so I started to investigate in depth) and the answer from those who claim to be experts is always the same: YOU CAN'T - even in posts of year 2023.

I don't want to sound arrogant or insolent, but I just find it incredible, I still don't understand this huge misinformation spreaded in every answer to the next question: "Can I extract the content of a WUA file?".

And finally, I want to thank you because I had no hope of finding a way to decompress a WUA, after hours of searching and reading (from people and developers insisting that WUA cannot be decompressed), until I read your comment.

The fact that CEMU doesn't provide a way to extract a WUA file it also may generate much more confusion. That is another thing I can't understand: the devs of that emulator provides a way to pack a folder as a WUA file but they don't provide a way to extract the generated WUA file?. What a devs... they don't event show a warning nor a visual cue (before you start the loadiine conversion to WUA) telling you that they don't support converting WUA back to loadiine in their own GUI for whatever reason.

Yup, I can only confirm your statement. .WUA can be converted very easily using zarchive.exe. I found this out by chance because I also wanted to know how to convert such files back. Simply drag them onto the .exe and you're done. It's just a shame that you can't use .WUA on the original hardware. Because all my backups are in this format. And by the way, the developer's website also points directly to this tool (version 1.27.0b). So it was always possible.
