for those that are still wondering how to use the cheat engine with this game, i'll explain the hardest (actually just more time consuming) stat to raise, which are the ones that have a value of 1. Money is the easiest cause its the highest value, so it wont take you more than a couple of searches to find it.
im assuming you followed the directions of the other posters and you've selected the right process and are searching for 4 byte.
first seach: 1 (physical) = bunch of results
(an easy step i often do here is search for UNCHANGED once or twice, that eliminates quite a bit of results)
eliminate/remove all the addresses that dont have a value of 1
go to gym, work out = raise physical +1
next search: 2 (physical) = less results
again, search for unchanged values, you can even go to a different location in game before you search for unchanged, that helps flush out other variables.
eliminate/remove all the non 2 addresses
go to gym, work out = raise physical +1
repeat searches until you have only one value that corresponds with the stat you want to change.
its super straight forward in this game, so those that dont know much about using CE can use it to practice finding values.
