Actually, it appears to me that it will not be that simple to keep an audio track in sync, since there are a couple of differences with Despecialized 2.0. Remember Harmy had to delete one frame at the reel change near the end of the movie (between Vader falling down and Luke following him to a circle hatch opening) in order to keep Hairy_Hen’s audio in sync. Also, there was an extra frame in the beginning in DE 2.0 that required a +42 ms offset.
This release may fall out of sync by 1 frame here and there but overall it’s unnoticable. The audio track used for this release was the high rez stereo option from Harmy’s Despecialized.
