I have created a set of files to create the correct driver set for the 1965 Cape South Easter Trophy at Killarney, South Africa. They are in the attached .zip file. Simply paste them into the top level of your main GPL folder - but make sure to take a back-up copy of your original driv65.ini file first, or you will loose the driver set for the rest of the 1965 season.
I have adjusted the speed of each AI driver, and get lap times that are approximately historically correct. It is not too hard to beat the AI like this, even I managed it. I suppose in real life they were driving local specials or older cars and not the latest works cars used by human players. If necessary adjust the hype value for each driver (in the .ini file) upwards until you get what you want.
This is my first attempt at any sort of Mod for GPL so please go easy if I have screwed anything up. Feedback is welcome.
If anyone could tell me how to move the starter so it is actually possible to see him from anywhere other than 2nd on the grid I would appreciate it.
