i recently got a hold of a ps1 system and ff7 game, the game played no problems all the way through the first disc and into the second disc up to the point where cloud and tifa fall into the lifestream together in mideel. the scene of them falling into the stream plays, they float down the screen, everything then goes white, and a buzzer goes off signaling it has failed to load, the game disc looks to be in great shape no scratches or anything. any suggestions??
