As I've mentioned before in response to the same comment you've made in every thread involving KI, paigeoliver, getting KI to work is one of my personal goals because it's a personally favorite game of mine.
I could just as well say "Why bother with Ms. Pacman when I can play Killer Instinct?" but I already know it's a pointless question. Why? Because Ms Pacman is a good game that lots of people enjoy. Well guess what... So are Killer Instinct, Cruisin USA, and Area 51. Given the choice between Duck Hunt and Area 51, I'd probably take the Area 51 in a heartbeat, but I know there are people here that would disagree. However, the whole point is choice and personal preference. You have yours and other people have theirs.
You think that if people didn't like these newer games they would even bother trying to emulate them? People aren't just doing it to have a complete collection. Hell, my own collection is probably missing a couple hundred games but you don't see me freaking out over it. Classics are good, but so are the newer ones. If I wasn't concerned with actually PLAYING Killer Instinct then I wouldn't care if it worked or not. However, I like the game and want to get it running so I can PLAY it. You play your games and let other people play theirs.
Ok I think any further comment on this subject would be redundant on my part...
