Hacking How to edit textures of models in Smash4 Wii U?

[LuckyJero]

Hello!

After several hours, I managed to get every single file of my Smash and have the chance, to change characters in general.

Now my question is:

What programs do I need to edit textures?

I got the following data (Villager aka Murabito for example):

data > fighter > murabito > ... (several folders)

Help?

Regards

Jero
