Put your name in as RAVIOLI. Now go to Multiplayer mode and select tcp/ix (i think). Then Select up the top Cheats and Supercar. Now down the bottom select the car you want, it's colour and your track you'd like to race. Exit the multiplayer mode and instantly select RACE!. WARNING: if you press cars or tracks in single mode you'll stuff the cheat.
You'll Race alone on any track with any car!
You'll have to do this every time you start up Powerslide.
