Thank you for responding. I tried the vacuum cleaner idea, but the thing is, I have done this from just starting the game system. Turn it on, go to the Bullring level, get the gold, the game freezes up after the video with the skaters eating it. It doesn't freeze up at any other point in the game. I have cleaned the disc and even resurfaced the disc.
As for the codes, I have been holding down L1 and it unpauses anytime I hit X. Maybe my L1 button doesn't work.
