man. I remember when I was in Middle School, I had Pokemon Red, Blue, and Yellow, and a couple of Game Boy Colors. I had every pokemon and Mew. but I didn't use a gameshark to get Mew. My uncle had gone on a trip to New York while he was staying in Ohio and actually went to a ....whatever you call it, and they were putting Mew on people's pokemon games. He came back and we did the copy pokemon trick where we both end up with the pokemon. I ended up having Mew on all three games.
Of course, this is the same uncle that, a few years later, stole my game boy color and my pokemon games, so that was the end of that. It was cool while it lasted, though. AND I was the only one in school that had Mew on my games.
