Just in case anyone's interested:

The emulation site Zophar's Domain still hosts Nesticle movies from ancient times, including some SMB1 speedruns. I have a 7 min 10 sec run on there from 1999, and the "record" progressed all the way to 6 min 30 sec in 2000. Not sure if they belong on official record progression lists, but I thought some here might find them charming if nothing else!
