I bought a used copy of Tekken 5 a couple of days ago and just got around to playing it and I noticed that there were classic arcade versons of the three original Tekken games.  I played a little of the three games and I was surprised how playable Tekken 3 was...even by todays standards.  There are some rough areas (which were smoothed out in the retool of Tekken 3...Tekken Tag Tournament), but over all still very playable, I was not so thrilled with Tekken 2, and Tekken 1 was just a nightmare to me.  But the one thing I was happy about was there were absoulutely no load times at all for any of these games in between fights.  Just jamming the start button as fast as you can a couple of times will get you straight to your next battle.
