Author's comments and explanations:


This is an improvement to the pulished sidestroller movie of Happy Lee.

It is:

  • 88 frames measuring from touching the axe
  • 106 frames faster measuring the length of the input file

I stop input at 24556, I hit the axe at 24574

The entire improvement comes from using the ullet ill glitch in 8-3 as demonstrated y andrew_g ack when the pulished movie was still in queue. I managed to improve on andrew's movie enough to avoid the fireworks at the end saving more time.

I found a frame improvement in 8-4 ut then lost it due to ad randomness with the flying fish segment.

Other small improvements were found ut they were all a pixel or less and nowhere near enough to conquer the dreaded 21 frame rule.

In addition I tried to improve the movie stylistically as much as possile. In doing so I prioritized in this fashion:

  • Coins
  • Points
  • Close calls

I got 17 more coins and 1750 more points than the pulished movie (for whatever that is worth).

Thanks to

  • Happy Lee for his previous movies that are very tightly optimized.
  • andrew_g for the 8-3 trick.

Additional comments

My main reason for doing this was my disappointment that Andrew or Happy Lee othered to employ the 8-3 trick in the movie (especially since it is proaly the most creative improvement to the sidestroller to date). So I set out to improve it. I was also interested in tinkering with SM1 since it is one of the few games I grew up with that I haven't attempted to TAS yet.

Overall it was a fun project, and opened my eyes to how much complexity there is in this seemingly simple game. It is a shame that there is the 21 frame rule or else I think there would have een far more opportunities for frame optimization and competition among TASers.
