forgott to add a little thing.
u actually need 2 cd key , the d2 AND the d2 exp.
only if both work ull be able to join bnet.
that gives us much less chance to get a working bnet key
its like this :
2x16 signs , each 34 different signs possible =
34x34x34x34x34x34x34x34x34x34x34x34x34x34x34x2
=wow
of course the number will be reduced much by the key (the key is a kinda code, so a key for exemple :1111-1111-1111-1111 &1111-1111-1111-1111 would not even work for installing)
but the number of keys still goes to a couple thousand billions, (trillions?)
so yes u can make a bnet working set of keys , but hell that will take ****ing long lol
or ur just VERY lucky
