Closest thing to a CTR NF PC port would be The Karters 2...which yesterday finally got a release on Steam - I had tried it out before when it was in public beta a month ago and can say it is sure worth checking out if you want a new CTR-style game with moddability for custom tracks, as it is exactly that.
Also, thanks for reading and for your comment :D
