When converting this game into a digital PKG package for installation on a PS3 hard drive, compression errors can occur. Many "unverified" downloads found on the open web suffer from the "Black Screen of Death" (KSOD) immediately after the title screen. A verified PKG ensures the EBOOT.BIN and the massive 40GB+ archive of game data are decrypted correctly for your specific firmware version (usually Rebug or Ferrox).
