Dave how did you find the hacks in the pub?

Hey Dave i have a small question. If you don't mind of me asking it here i got... I was just wondering how did you find the hacks posted below. When i ask how did you find them i mean did you use cheat engine and if so what did you search and how did you get the right addressee/value.

-No Fog
-No Spread
-No Recoil

Well those are the basic three i would like to know how you found using cheat engine or however you found them. I would love to know how you made chams/wallhack but i don't think you used cheat engine for those and i am only good with cheat engine.

FAIL to you triple poster.
