  • Thanks man best cracking

  • Well once again this is just plain stupid patching (that's how it's called). Redirecting the badboy jmp to the goodboy jumps isen't the right solution. You could easily serial phish this crackme. Dont try this on real applications tho, it'll still make your program unregistered.

  • Can someone tell me how to get a serial if there are no referenced strings and there are no relevent intermodular calls?

  • get a better micropone

  • Sry but if I would not have known what you did, I had no idea, because I did not understand any word...... Can you please write, what you did, in the info-text so that we can understand what you are saying and doing?

  • Find a better microphone
