Why use validation at all ?. Unless your aim is to annoy your users, why do you want to use it ?.
Anyone who wants to steal your code can do so with ease. I stopped protecting my trainers after i realized it is pretty useless and also causes annoyance for users because AVs flag it falsely as virus becuase of the public packers. If big ass companies can't stop crackers from "raping" their products and we're talking about professional DRM here, how do you think you can stop anyone ?.
There are so many skilled people in gamehacking alone who right now could be laughing at your drm (and the upcoming ones) thinking how stupid it is, and i am just the only one to tell you publicly that it is shit.
This is just my 2 cents...and i could care less what you do. I am more worried about
