at the begining in the cementery you have 10 intelligence(search 10 in cheat engine), after you pick up the phone and choose the int option the value goes up to 15, use cheat engine to search for this (next scan, not first scan), remember when searching change the value type from 4bytes to float. Dont pause the game while you do this, after the search you will have a lot of values but most of them will be changing, search fot the ones that dont and try changing the values 1 by 1 to 100, once you know witch one is the intelligence delete the others. If you want to change the other attributes all you have to do is add the manual address, for example you alredy know the address for intelligence, lets say is 278750C87C, the important numbers are the las 2 (87), go to add address manually and star adding the same but change the number, 278750C86C,278750C88C,278750C85C,etc. those will be for the other attributes
