very nice, good mix of speed and tech.
Only nice MediaTracker intros are missing, but that's not at all dramatical
D-Speed I: the 3rd and 5th CP do not work properly, the next jumps are impossible (ok, you have to be fullspeed across the whole map

)
How do you manage the first boost and the turn before the looping?
D-Speed III: it took me a while to get the speed (min 300km/h) right at the jump before the looping
The others are ok, the looooon boost is funny the first time you see it, but it somehow repeats on the next map.
D-Speed X is very nice
Gold is easily reachable, on some also Nadeo. Try hard to improve your validations
Thanks for a nice unofficial extension of the solo campaign
