Not mastered but probably streets of rage 2. Unless its on points, not sure how to do a contest on it. Funny, I was just thinking this topic a few days ago.
As for tournaments. I won a random game on the original xbox for playing burnout revenge before it released. Whats cool is it was a knock out tournament and every time you won, you got to pick a brand new PS2 or xbox game. I got 1 and my friend got 2.
