Of Course not. Quvack and Myself made the cheats for this game especially for the PJ64 1.5 release I think Q has some more somewhere im sure he will dig them out
As far as I remember all of my codes went into the pj64 cht file, they should all be in there for you, I havent been able to track down the database of the cheats that I've made in the past, but I'll look more when I have a chance.
THPS3 taught me a whole lot about making cheats! along with Gent's help =)
