Crash Bandicoot screen cut off
 

Doesn anyone know why when I play the Kalisto release of Crash Bandicoot warped on my US PS2, the bottom inch of the screen is cut off? I thougt it worked as NTSC and PAL. Ive also noticed that my Ver 1.3 of GameShark appears to have part of it missing in the lower right corner at the main screen? Anyone else have these problems or know the cause?
