OK, first of all, I have to state some things:

The JJ2 shareware is not full version. It is the equivilant of a demo. Second of all, DO NOT DO WAREZ. No matter how tempting it may be, Warez is wrong and not good. Besides, there are risks involved. Certain individuals will give you working copies of JJ2 for free, but just don't accept them. Buy the game yourself. By doing Warez, you are indirectly killing the game.

Not that I think you would do it. I'm just saying that I strongly recommend against getting JJ2 that way.
