Unlock High Res Mode

To unlock Hi-Fi just finish all Arcade Mode tracks on hard using A, B and C level cars.

I found the best way was...A - Choose Honda NSX
B - Choose Honda Prelude, if you cant overtake the leader,choose Integra R, its better on the twisty bits.
C - Choose Honda Civic.. easy, till you face another Civic!
