I have played this version, but not competitively. As far as I know, this guy has the highest score and it did not reach a killscreen. But there are some interesting differences. The N64 version does not have barrel control, and levels 5+ still have type 2 wild barrels. He says that there are some safe spots on the barrel board where you will never get killed by one of these wild barrels. This means that they are pre-programed and are not influenced by Mario's position. Once a fireball is smashed with the hammer on the pie factory, it will not respawn. Fireballs on any board can go up and down all ladders at will, even coming down from the kong conveyor, or rising as high as pauline on the barrel board. The range that one can hit a firefox or fireball is much larger, sometimes just next to it will cause a smash. The jump over to the small platform on the spring board needs to be more precise, there is a larger margin of error but mario's ascending and descending speed on ladders is about equal to his left and right movements, making it easier to time the springs or escape a fireball/firefox. The lower conveyor does not change direction when kong reaches the far left edge of his conveyor, rather the change in direction seems to be a set time integral that does not correlate with kong at all. I have thought about learning and streaming some attempts to get familiar with it.
