Quote from TJF588:
At what time did you pause that? at the end of the timer countdown (which would mean p good reflexes to get something accurate) or after the cutscene (which in itself isn't part of M1, so it should count)?
It looks like he paused as soon as he got to the Zero Suit Samus part (before you get inside the mothership). I think it would be more accurate to pause at the elevator out of Tourian, as that's where the playable part of Metroid ended.
