I have published initial version of the NFS4 Modern Patch. Currently, it has a small amount of fixes. Unfortunately, I had spent more than 150 days during last year on developing of the NFS3 Modern Patch, it is too much, and now I can't afford to spend enough time for porting main useful changes to the NFS4. I recommend you to try the NFS3 Modern Patch to understand how big and useful this NFS4 version of the patch could be.
This kind of work needs much time. It is not possible to do such things spending only an hour or two in the evenings. It requires days and weeks of hard work without huge gaps, 8-10 hours per day. I had started NFS3 Modern Patch a year ago, and little by little this project absorbed all my time and had taken the place of my paid work (freelance). Now I can't continue in the same spirit because I'm almost out of money. It's time to choose what I will do next.
