Does anyone know if you can do the CD trick like you could on the PC version? You were able to put a regular cd in and the tracks on the CD would replace the radio stations from the game. I tried doing it on GTA2 but it did not work.

Nope.. On the pc version you can install the whole game to your pc and just use the cd for the music. Playstations read it all from the cd..

I wish more games did this the ridge racers did, as does the slightly obscure hoverboard game called streak. there are more that I don't remember.
