Just start a normal game of ridge racer and when you start to race, pause the game. Open
the CD thingy and take out Ridge Racer. Next, place the music CD in, close the cover and
play. Now, you will be able to play all of Ridge Racer and listen to your own CDs.
will not harm you PSX in any way. If you don't want to listen anymore, just put the Ridge
Racer CD back in.
