Hacking [release] GTX Extractor

AboodXD · Jul 31, 2016

GTX Extractor v5.2

It can also convert DDS back to a .gtx file.

Why so complex?

Wii U textures appear to be packed using a complex 'texture swizzling' algorithm, presumably for faster access.

FAQ:

How do I run this on my Mac/Linux (Ubuntu)?

You need to run it from source code.

There's a crazy bug that is going on, there's no reason for it..... >.<
I'm trying my best to fix it!

CuriousTommy · Jul 31, 2016

Keep up the good work, I can wait for all the formats to be supported. No more proprietary tools!

(Also, thank you for the Linux support!)

Don't try this, I'll update it first then I'll tell you if you can use.
There's a weird bug...

AboodXD · Jul 31, 2016

@CuriousTommy It's safe now.

Everyone who downloaded this, please download it again!

Warning if creating a BC3 (DXT5) .gtx file:
The path to GTX Extractor must not have spaces in it!!

AboodXD · Aug 1, 2016

Here's a video of testing the results of GTX Extractor:

What I did was:

Extracted the original .gtx file.
Edited the generated .png file.
Created a new .gtx file using the edited .png file.
Tested the new .gtx file in game.

What's changed since v1.1? I can't seem to find the original thread to compare, nor my posts from that thread. Was it deleted?

Yes, because this version (v1.4) is completely different. (At least to me)

If you want to compare, here is the old one and here is the new one.

GTX Extractor in action:

AboodXD · Aug 15, 2016

GTX Extractor v2.0 is finally here!!

Changelog:

Added a new swizzling method, which adds more supported formats!
Sacrificed the .gtx file creating function (because a bug occurs when using the new swizzling method), but I promise I try to add it again.

@CuriousTommy I think you'll like this update!

Please note that as of this version, the "creating a .gtx file" feature was removed.

AboodXD · Aug 19, 2016

I'm back with version 2.1!

Changelog:

The .gtx file creating function is back!
Did some cleaning up and bug fixing.

I just want to say that naturally this program should support more format than listed above, but those listed above are the tested and working formats.

Is it possible to add support bffnt(font) files?
Here is a script transforms them into gtx for QuikBMS.

It's possible, and so is BFLIM.
I can add both of them.

AboodXD · Aug 26, 2016

Adding BFLIM support in the next release!

The extractor is pretty much complete, I just need to do some ingame tesing.

New Features:

Extract and create BFLIM files.

AboodXD · Aug 27, 2016

This BFLIM Extractor literally took me 10 minutes to write. :rofl2:

Zarklord · Sep 9, 2016

hi i was wondering if you could add support for this gtx
and yes before you ask it is legit
even though it might seem like it isnt
this came from inside a .pctl file from smash 4 and the game uses them
though for what im not sure...
