You are wrong, root doesn't cause that to ur phone, that it is caused by a bad use of root users, you need to know what u doing and why, plus you need to have an app to act like a guardian to your device (SUper users apps like, Super SU, Superuser, etc), i got mine rooted and I'm getting the most from my phone.
You need to get more inf bout it bro.
Best regards!
Oh and i was looking for an app like Cheat engine haha, I'm currently using game killer cuz It let you make different tweaks at the same time, plus it has a memory editor, or hex editor, so I recommend that one, while it comes Out somthg similar to Cheat Engine
