Serial = inverted name + name + 24

Eks.: name = 1234
Serial = 4321123424

Javascript keygen below;

Code:
<script language="JavaScript"><!--
function strrev(str) {
   if (!str) return '';
   var revstr='';
   for (i = str.length-1; i>=0; i--)
       revstr+=str.charAt(i)
   return revstr;
}

_hw = "ksbunker"; // Username
_rev = strrev(_hw);
alert(_rev + _hw + "24") // Generated Serial
//--></script>

Works backwards too. Guess it's still considered reversed + name + 24 Very Happy

e.g.:

Name: emaN
Serial: NameemaN24

Heh Razz I admit it was fun to trace though Wink

Instead of changing JNZ to JE. Just change the Z-flag from 0 to 1. All it takes is a single click.

You know you've cracked it when you figure out the password, usually. I honestly am not encouraging patching of the file (when it's asked not to use patching), but it can be a good practice. Thing is, by using it a lot, you get used to it, then get stuck in your "world of patching", not willing to change your stance Wink
