• I am trying to play Katamari forever and it says it is installing trophies, then it stops and says this "trophies must be installed on PS3 System HDD....what does that mean...it has let me play the demo before but not this.....we rented this game too from Gamefly
  • Sounds like the game disc may be a bit on the abused side and the PS3 can't read the data to put the trophy data in place. That data would not be with the demo.
