You could try and go to gamefaqs.com... probably you find help there... when i need something of that kind, it's the first place i go to... and don't worry, they don't have only faq's and walkthroughs, they have cheats section also... or you can try gamewinners.com, though i don't know if they have cheats for that specific game... hope i helped... see ya... :)
