@quicksilver Awesome job on the fairly grueling calibration of Hard Drivin. Can you, by chance..please share your nvram for this or any other similarly minded games! That would be absolutely awesome! I am hoping to do as many of the more complicated Racing Game calibrations, as feasibly possible. And, these calibrations, we can make permanent, code wise, too! That way, noone will have to calibrate them in future revisions of our MAME code base:) Already have many done, such as Carnevil, Terminator 2, Revolution X, etc, etc.
