What exactly are you trying to do
You're not explaing things very well
and using the cheat too much can break your game, forcing you to start all over again.
if you want to do Billy's path, my recommendation is to start a new game and follow the walkthrough step by step
I do not recommend trying to follow your own path in polaying the game, you'll just get lost in what to do next to progress. while it's a nice game it's not very well put together.
to activate Billy's path so you can do his scenes you start with step 58
