they are showing off but what they dont realize is that they will all be patched at once.. Nexon only has to change a few things about the game in order to patch / detect all the hacks that are currently released.
and if i'm not mistaken nexon will try to drag something to server sided so it will no longer be accessible as a hack.. however this would increase the game requirements
hopefully OPK will soon be server sided.. its possible, all they have to do is change one of the addresses for it to server sided and OPK is gone. OPK runs off X,Y, and Z axis addresses so if they were to take the Z axis and make it server sided OPK would be no more.. btw the Z axis would be how far away the character is from your position.
