1, they are server sided... If you hack them, you'll get busted very fucking easily, Nexon will find you... And you get jailed.
2, How about make your own bypass, rather than hope to god everyone makes the shit for you... Even using olly to make a HShieldless Engine.exe would be faster than waiting for it... Sure, takes a while to make, but is just as effective...
3, Seriously... Learn something rather than leeching it all...
4, Before you even ask, NO! I am not giving you my bypass...
