Hacking Wii U image (WUD) compression tool

[Maximilious]

If I compress my WUD's, are they still readable and dumpable by Uwizard? 24GB per WUD is unbelievable and my 6TB NAS is already chok full!

No, because UWizard use crediar's DiscU, which requires uncompressed ISO to extract it.
if you compress the ISO, you will have to decompress it before extracting its content.

Ok, but decompressing is also easily done using this tool right? Just making sure before I go through the work and invalidate all my WUDs haha

 

[Exzap]

Yep, can uncompress just as easily as it can compress.

Great work on the tool. However is there any reason for us to keep a .wud after everything has been extracted from it?

I'm keeping mine just in case down the line we can play them directly from .wux format and I don't want to bother redownloading them all again.

I would think if another loader ever came out it would also work with extracted files. I'll hang onto them for now I suppose

Cemu can only read WUDs, so I suppose that's reason enough

It can read WUXs too.

It can read WUXs too.

Are there any scene releases in WUX format??

No, they are all in the WUD format.

This tool works really well. Compresses/decompresses by drag and drop, and also validates each file after the operation. It also compresses really well, the biggest games I have are around 12GB now and smallest being around 1-2GB.

 

[TotalInsanity4]

Oh *facepalm* I understand now. Sorry, I figured that a compressed WUD would work with Cemu, but I didn't ever make the connection that the file extension is WUX lol

 

[sonic1000]

When I tried to compress a WUD, the program just opens and then closes immediately.

 

[Wurztha]

Are you dragging and dropping the 24GBish .wud onto the compression tool?

 

[sonic1000]

Yes.

I was thinking if we got 'full emulation' or something with an emuNAND-style setup for online play the WUD would be handy.

RAR5 does marginally better than WUX at compression but it takes quite a while longer.

 

[Wurztha]

I thought the same with rar5 but it seemed to be game specific. One would always do better than the other so test both

SM3DW was one I believe, RAR was 5GB and tool was 2.6ish.

Considering how the compressor algorithm works its surprising that RAR couldn't consistently do better. I compressed a WUX file and it went smaller rather than bigger so I thought winrar could just always do better. Used best setting with 64M block setting iirc, was about an 18GB WUX, compressed to ~17.2GB

You have to take into fact that 'they' put multiple copies of the same file on the disc in case of a scratched disc. And also most game companies compress things as best they can anyway to optimize loading and disc space.
