I remember having the same fun with my friends playing this game, which is indeed a very good Mario Kart clone for PC. Here is a screenshot to fresh up memories:
As for the multiplayer online matter, the game used to have a strange online program - site for playing on the internet. It was called "chatnplay" (there is a chatnplay.exe file in the CD - hope you can get smth out of it..)
Anyway the game is not playable yet with newer cards, as it uses a "setup.exe" for the video to be configured - which unfortunately can't even detect my vid card!! As a result I get software rendering in 320*240 of the graphics on 1650*1028 widescreen... LOL :p Hopefully I'll get in touch with Timesleep and see if he can fix this problem. (as he did with CS

EDIT: PROBLEM ABOVE IS NOW FIXED!! ----> Seems I had to clean the NVidia drivers with "Driver Sweeper" LOL After that the setup.exe detected my vid card and playing in 1024*768
