Just a note...there's a difference in the rules between the bounty and the official settings shown on the Twin Galaxies link.
The link says: "Rules: Difficulty : 2-Normal. Start Units : 2. Extended round : On. "
The bounty says: "difficulty = 2 (Normal), starting lives = 2, bonus life = None, Game is OVER after last event"
I believe this means that you get only 1 pass through all of the events. When you finish the high jump, you're done. That is a setting on the game.
That also makes more sense, because 98,000 is an unbelievable score with those settings.
GGK - you're right, it's technique. But, you'll probably have to shave another second or so off of your 100m, and have similarly great scores in the other events in order to break the 98,000.
