I'm no longer updating this thread regularly...
Now officially the largest thread on MKWii General Board!
This is the official home of Texture Hacking in Mario Kart Wii! This thread will also handle terrain-type (flag) hacking, should anyone ever try it.
Basic work on model hacking has started! Head here to take a look:
The Official Mario Kart Wii Model Hacking and New Courses thread!
As some of you may already know, a while ago me and my younger brother discovered how the texture files for Mario Kart Wii are stored, along with how to modify them. So, us and now many other hackers have been changing textures around and creating videos of the results!
NONE OF THESE TEXTURE HACKS WILL WORK ONLINE. Only the texture hackers are able to view the changes that they made.
A video tutorial of how to do these texture mods can be found here (thanks to Lol-Alex!)
Texture hacking's only limited by the user's creativity (and a ton of technical stuff, but I can't be bothered to explain all that. Most of the time, if you put a picture in, it'll just go and work

)

If you want to try texture modding for yourself, download this app:
SZS Modifier
You will need a Mario Kart Wii ISO and a way to extract SZS files from it. You can view all the textures in the game, and make changes to them.
If you actually want to test your texture mods, you either need the Dolphin GCN/Wii emulator, or your Wii will need a way to boot fake discs AND NEEDS TO BE v3.2 OR LOWER. Or you can send modified SZS files to me and I'll play them on mine and make vids if you want.
