Sorry to bump this, but I have had some interest in the "car physics" thing. Unfortunately all the download links in this topic are dead. Any chance that anyone still has the file and could put it up on Dropbox or such?
Wow, have I really been around here for nearly 2 years!? lol
And sorry, no I don't have the cap that I downloaded at that time.
I'm pretty sure that the computer I was using then is now in my MAME cab, and I know I formatted that before I installed it into the Cab.
Maybe Deadeye still has it somewhere.
