Talk about a blast from the past with a hack hailing from the year 2003 if RHDN is to be believed.
Review:
From a moderate understanding of Mega Man 2 speed tech this seems pretty solid. Unnecessary jumps don't seem to be present here, which is good since walking is slightly faster. There was a moment where I noticed crash bomber being used on Quick Man when it did 1 point of damage but the refights showed that the buster did the same damage and the previous weapon choice on Quick Man was to save menuing time.
There is one known improvement that I know of involving
ghost platforms resulting from the
egg swap glitch but this is something that would save subpixels. Small improvements like that would involve an incredibly high level of optimization work, alongside other factors such as frame rules, to implement and save small bits of time.
I also found this user file from Shinryuu that only goes through Air Man's stage up to entering the boss:
User movie #637931607312440317
This submission does reach the boss door sooner than the user file. As far as I can tell there's no other known TAS records that I can compare with.
