I noticed that the forum for GT4 is not well used. Also, I was prompted to come here from a site listing GameShark codes. My Question: (pls. redirect me if need be). I would like to know if there is a Gameshark code to unlock all the courses at once in GT4. If this is some kind of forum for purists, I wonder why the gameshark questions are also here? But, I a a retired fellow with an penchant for this old game and just now realized I will never live long enough to unlock all the courses and could sure use info on a cheat for all courses before I spend money on an old gameshark disc etc. Thanks.
