Drift code: 

Go to the top left room of any corner. 
Press and hold (up+left)+L1+R1+start. 

If done correctly the game should then freeze. 
Then release up,left and L1. While still holding 
R1 and start, press ( down+right )+ triangle. The 
game should then unfreeze and you would have the 
ability to drift over walls by R1 and by pressing 
L1 would lower you down. Obviously use the D-pad 
to go wherever you wish. There is also a secret 
area in the first level. Go up the left stairs 
and go to the left wall and drift over it. Go down 
and you sould run right into it.
