Cheating was straight forward, 4-byte value. Starts between 60,000,000 and 70,000,000. Freeze around 17,000,000 for maneuverability. Hold down 'z' for brakes and just ride through. I'm not sure if it was a glitch, (I had several graphical ones), or if planned but the orange does not have a flag. Like I have reloaded it several times and each time is the same and I ended up flag-less. Also to further note my curiosity I ran the game through IDA and there isn't any functions or naming related to an ending as the instructions confer.
No ending, good waste of two-hours of my weekend though .
