Advice
I know he fails to mention this but i feel it's pretty important to note. If you value you're account or it's your main that you've been on for awhile and care about, don't bother with it, All it does it change the game.cfg in real time and adjusts the parameters. which is 100% detectable by Riot. They will just ban you during the next ban wave.
Buuuuutttttttttt if you dont care about the account being banned go for it! it's a solid chunk of code
