Was a pretty solid run for the amount of preparation I put in. My major mess-ups at Laythe almost cost me the record. The video also includes an earlier aborted attempt, you can skip that bit. Did not beat the record by very much. The game crashed twice, I paused the timer until I resumed the save in both instances. There was one point where I accidentally reset the timer, around Ike, but I quickly restarted it. The two end times are approx. 1:05:19 and 5:27:31 with around 4 seconds of time where the clock was not running. Stream quality is not the greatest, I haven't rewatched the whole thing but I believe I noticed some dropped frames. Yaaay gotta love my bad internet...
Mod edit: Retimed to 6:35:42 (Time continues to run even in the case of a game crash).
