I have got the actual Arcade version of the game on my pc. My step brother had the emulator & he burned onto a disc for me. The only prob is for some reason the colours are all weird & the sound is sketchy, so the game isn't working right on my comp for some reason. But BT, I can send u the whole emulator complete with games if u wanted.
I think the first time I actuallty played the arcade version was when I was about 7 or something. I knew as soon as I saw the arcade machine with "Alien vs Predator" written on it that I would be playing it for ages, I actually remember spending nearly $30 in that arcade playing that one game in a single day. Although it might be fairly weedy in comparison with AVP2 & the like, it's still a great retro-style game.
