According to http://speeddemosarchive.com/CutthroatIsland.html the 14:29 run is actually from April 7, 2012; the date January 2, 2014 is just when the video was uploaded to YouTube. Not sure how much it matters, but I just figured I'd mention it here

@Koro Thanks for the hint. I recently became mod on this board and will change the run accordingly. I will also look into timing rules for SNES as there were none so far, so the run might also be retimed.
