Cool, off to try StuntCar.....

Speaking of Stunt Car Racer, the Amiga *cough-bastards-cough*  did something called TNT (The New Tracks), a homebrew patch.

It would be kinda cool if we could "steal" the work for the atari version

If someone was willing to patch the menu screen to access the new tracks, I'll extract from the patch (or mail the creators) and get hold of the data for the new tracks.
