I'm realizing your carset is too heavy for my computer
Which is great, actually, as it seems the graphics of the cars are really cool and detailed. The graphics of the cars were made by you, right? And the sound is quite cool too, does it come from http://grandprix2.de/sounds/sounds.html?
I'm asking because I don't contribute with anything - whenever I share stuff of mine, here, is based on combining materials developed by other people. Mainly, I do carsets taking on cars, helmets, etc., developed by other people and applying some Performance values of mine.
What I can do is to provide a 1975 version with my choice of 16 tracks (developed by other people, allow me to insist) and then you can put your carset in it.
