I never played the arcade version of Yie-ar Kung Fu that much but I played the Commodore 64 version a lot. I got to the point where I could beat all of the characters multiple times. It's been a while though so I'm not sure how I would do now.
I don't own any arcade games and don't really have much room for any (I suppose I could get rid of some stuff in my computer room and have room for a couple). I really want to acquire a MAME cabinet one of these days...
