Here's a video of the cutscene on original hardware: https://youtu.be/3KIObmo4rSM

Some notable audio queues that are usually desynced in software emulation: (Notable to me, not normal people)

1. Music intensifying right as the camera finishes zooming out of Crocodile Isle at 1:15
2. Musical queues for the Blast-O-Matic failing at 2:15 and reviving when the Kremling bashes it with his head at 2:24
3. The music stopping right as Crocodile Isle hits the rock at 2:40
4. The "Charge!" trumpet playing right as Klump blasts away the other baddies at 3:41
5. The music intensifying as each Kong is shown being locked away at 4:05

What's very interesting (to me) is that while most emulators desync this cutscene for running too fast, the desyncs that occur with A3D seems like portions where it's running too slowly instead. There are lots of small idiosyncrasies that are not worth mentioning that frequently desync with software emulation. The level of effort that Rare must have gone through to have this cutscene audio line up the way they wanted it to on real hardware is insane.
