I recommend they give me a free battery replacement for my copy of Silver that hasn't successfully saved a game in years. Emulation just isn't the same.
It would be great if it was possible to catch Larvitar early in G/S. Tyranitar is my favorite second gen Pokemon. Also, I'm more of a realtime combat guy, so I'd like to see that somehow incorporated into Pokemon. Not sure how that would work, though. The closest thing thus far, I suppose, would be Super Smash Bros.
