Please note there is one false start before the true start of timing due to the additional exposition at the beginning and forgetting to start the non-commentated version. The true start is at 7:36.

My non-commentated version of this video got the audio and video out of sync when I tried uploading it to YouTube, even though it is in sync on my computer. I briefly paused emulation AFTER timing stopped, but never during or before.

Still, this is why I "double-record" like this. If one fails, the other will still likely work. You can see the exact action with the Fusion recording in this video.
