Nordschleife theme mod I've done a couple months ago but then broke because of the DLC that came out.Enjoy.
Now it works again. And I finally decided to release it on RD for easier download and updating for future problems.
I could not make everything blue and white but the theme is done for the most part. I'll be making variants of this theme sooner or later.
Please read the readme.
The theme does have a tiny slide show going on from time to time where it changes backgrounds.
