GTX Extractor v5.2

GTX Extractor is a tool which extracts textures from the GX2 Texture ('Gfx2' / .gtx file extension) format used in Wii U games, and saves them as DDS.
It can also convert DDS back to a .gtx file.

Supported texture formats:
  • GX2_SURFACE_FORMAT_TCS_R8_G8_B8_A8_UNORM
  • GX2_SURFACE_FORMAT_TCS_R8_G8_B8_A8_SRGB
  • GX2_SURFACE_FORMAT_TCS_R10_G10_B10_A2_UNORM
  • GX2_SURFACE_FORMAT_TCS_R5_G6_B5_UNORM
  • GX2_SURFACE_FORMAT_TC_R5_G5_B5_A1_UNORM
  • GX2_SURFACE_FORMAT_TC_R4_G4_B4_A4_UNORM
  • GX2_SURFACE_FORMAT_TC_R8_UNORM
  • GX2_SURFACE_FORMAT_TC_R8_G8_UNORM
  • GX2_SURFACE_FORMAT_TC_R4_G4_UNORM
  • GX2_SURFACE_FORMAT_T_BC1_UNORM
  • GX2_SURFACE_FORMAT_T_BC1_SRGB
  • GX2_SURFACE_FORMAT_T_BC2_UNORM
  • GX2_SURFACE_FORMAT_T_BC2_SRGB
  • GX2_SURFACE_FORMAT_T_BC3_UNORM
  • GX2_SURFACE_FORMAT_T_BC3_SRGB
  • GX2_SURFACE_FORMAT_T_BC4_UNORM
  • GX2_SURFACE_FORMAT_T_BC4_SNORM
  • GX2_SURFACE_FORMAT_T_BC5_UNORM
  • GX2_SURFACE_FORMAT_T_BC5_SNORM

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.

  • How do I run this from source code?

    On Windows:
    All you need is to install Python 3.4 or higher and open "gtx_extract.py" using python.exe.

    Other platforms:
    All you need is to install Python 3.4 or higher and run the command "python3 gtx_extract.py".

  • How do I build the source code?

    On Windows:
    After installing Python 3.4 or higher, install cx_Freeze and open "build.py" using python.exe.

    Other platforms:
    After installing Python 3.4 or higher, install cx_Freeze and run the command "python3 build.py". (build.py was tested on Windows only)

Download.
Source code / Github.

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!)

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


What I did was:
  1. Extracted the original .gtx file.
  2. Edited the generated .png file.
  3. Created a new .gtx file using the edited .png file.
  4. 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?

GTX Extractor v2.0 is finally here!! :D

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.

I'm back with version 2.1! :D

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.

this came from inside a .pctl file from smash 4 and the game uses them
