Today, I’ve done up my first track texture hack for Mario Kart Wii. Basically, what I did to Mushroom Gorge is change the sky coloring, and adjusted the ground coloring as well. The cavern part of the track is still the same as the original.
The download link below will contain two SZS files. One is for the 1 player races, while the other is most likely used with multiplayer races. Enjoy.
