CS cd-key changer?

[VashX]

yea... so... i was wondering if anyone knows how this thing works. i heard that u can add more than one cd-keys but then how do you know if it'll work or not? wouldn't u need a valid cd-key?

Note: I dont think this is illegal but if it is, then i'll delete it :p

yes, it'll illegal. Cracks, key-gens, patches, trainers, etc. Those all contain various forms of illegality.

Unless it came with the game.
