I only can save when cd CD1 is in the psx because the cd don't stops and I can't change it. When the message that I must insert the CD2 appears, the CD1 stops ( when Snake goes down the stairs ), then I can change the CD to the CD2. But in the screen appears this message until I press all the buttons. Only if I reset the psx desappears, but then when I load the game at the same point appears the message that needs the CD1. ????
