So I've been working on the HUD and I'm nearly there as you can see from the attached image. I've upscaled and/or redrawn the overRev, the rpm gage (still not for all cars), the shifter and the mph numbers. I still need to do the blue mph numbers (when you are drafting), the mph/kph symbol and the white letters used for time and ect. I'm just doing this in between sessions of FF testing (still need to add that spring variable I mentioned before).
I finally found the true Over-rev variable in memory which is great because both the rpms and the light were previously estimated, which isn't great for speed runs. The reason it took me so long to find it is because it's oddly a analog value (or at least whatever I'm using is). When you are nearing the max rpms it counts from 0 up to 127. 127=over-rev
So that's one more mystery solved. Again, I'll do a release just as soon as I can make time to gather up all the bits and pieces.
