fastest and easiest way to modify a CC driving-line when modifying or creating a new track?

What is the fastest/easiest way to modify the driving line when modifying or creating a new track? I have read about using a "save game" exiting gp2 and then modifying the cc line in the track editor. Then you can load up the game again- load your save and then see your changes quickly.

Has anyone ever thought of using "save states" like dosbox-x has, or modifying the value in the track directly in memory live? I was trying to think of a way to do this faster since from what I understand it is mostly trial and error. I'm wondering if any of the newer dosbox tools allow for this.

I started building the KymiRing and got as far as having the track laid out but stumbled at the CC line, it seems so convoluted! Given up on it now but if anyone can help with how to do the CC line I'd also appreciate it!
