Hello, I recently purchased an oldie but a goodie, "Titanic: Adventure Out of Time." I ran it on my Powerbook G4 (not Intel based) and it opened Classic, but said I need a system folder for Mac OS 9.1 (or later). I do not have the installation discs that may have supposed to have come with the computer. How do I get this old school (1997) game to work on my PowerBook? Thanks!
