What do you really want? You want the manipulated serial to be equal to 5439h (wich is the value calculated from your username).
So we start out with XOR'ing 5439h with 1234h. You'll get the value 460Dh. As I told you before the program converted from dec to hex, and we want the dec value. So we simply convert
460Dh into dec, wich is 17933, and this is the correct serial!
So, the correct match would be: Cruehead - 17933
There, I hope you understood it all...if you didnt just mail me!
See you later!
