    Re-encrypt Wii U Games?

    So it's known for 3DS but not for Wii U? Is that the implication here?

    Re-encrypt Wii U Games?

    You can decrypt Wii U games using CDecrypt, but is there any way to re-encrypt them? I'm interested in this because I want to maintain a one-to-one transformation between a more compressible, decrypted format and the encrypted CDN No-Intro format. The benefit of storing the files in a decrypted...

    Hacking Encrypting CDecrypt'ed files

    I am also interested in doing this. Did you ever find a solution?

    Efficient way to store backed-up MLC file?

    Regarding this comment, are there any examples of how to do this anywhere? I'm not sure how to do it from reading the command line tool help.

    Efficient way to store backed-up MLC file?

    Hi, I recently made a NAND backup of my Wii U and I noticed the MLC files are quite large (totaling 29.6 GB over all 15 parts). I threw them into a solid .7z archive (4 GB dictionary, level 9) and was surprised to see they only compressed down to about 25 GB, even though I only have system apps...

    Any reason to keep encrypted Wii U game files?

    I noticed Wii U Downloader implies the decrypted files are for use with Cemu and encrypted are for use with a Wii U console. Does this mean you cannot install the decrypted files on the Wii U? Is it possible to encrypt the decrypted files (is there a program that does this)? Basically, for a...

    Best way to compress WiiWare games for archival?

    I ended up using WiiPy (built on libWiiPy) as I found it was giving me a conversion closest to the original .wad file, even though the repacked wad file was still slightly different than the original. To remedy this, I used bsdiff4 in Python to generate a patch file which could be applied to the...

    Best way to compress WiiWare games for archival?

    Thanks for the suggestion, I gave Sharpii a try but it appears to be producing a shorter file. There are also a few other segments that are different too. It is much closer to the original file than ShowMiiWads was, but it still isn't producing an identical file. It's possible I may be misusing...

    Best way to compress WiiWare games for archival?

    Thanks for mentioning this. Sure enough, it looks like encryption was the issue, not the games' asset compression. Here's a comparison: The European, USA, and Japanese light trax .wad files take up 63.2 MB in total. Compressing them with 7-zip with a 1GB dictionary, level 9, solid block mode...

    Best way to compress WiiWare games for archival?

    Do you know if there are there tools which can decompress the .app files? Do you know if the compression standardized, or does it vary game by game?

    Play Old Brawl Mod in Dolphin Emulator?

    A long time ago a friend gave me a Super Smash Bros. Brawl mod with a ton of custom characters and stages that he made. I still have the files, and it does still work on original hardware, but I'm wondering if it's possible to play them in Dolphin emulator somehow.

    Best way to compress WiiWare games for archival?

    One thing I've noticed is that European and USA WADs are mostly different from each other binary-wise. For example, Art Style Light Trax has only a tiny portion of the files identical at the beginning, and then the rest of it is different, even though the games themselves are mostly identical...

    Best way to compress WiiWare games for archival?

    Is it possible to decrypt/unpack/uncompress WiiWare .wad files into a format that compresses better? I'm not sure what the deal is but compressing the .wad files with 7-zip/winrar/etc. gives pretty much no benefit. Ideally I would be able to losslessly convert back and forth between a .wad...

    Convert Wii CDN to WAD Files?

    I was not aware of this tool. It seems like it might do what I need, but I'm unsure. Reading the github, it does mention that it only supports this for "free titles" so I don't know if that will be a problem. I will need to try this out sometime later.

    Homebrew [Request] A tool for Encrypting/Decrypting .cia Files

    Did you ever figure out a solution to this? I'm interested in achieving the same thing. Edit: Actually, it looks like this fork of ntool can do it with the "cia2cia" command: https://github.com/Dimensional/ntool
