I picked up a copy of this game today as I read a piece about it at Dreamcast Junkyard. Released in Europe only it seems. Seems the online game ran on Gameloftservers; here's a picture of the online lobby I found (taken 2002/2003):
Seems there was also a Dreamcast clan who regularly raced on this game:

And look...it seems the Gameloft staff were not even aware this game was released and online was only activated in 2002!!!!
