Description
The movie was made in BizHawk version 2.5.2 and with the Sameboy bootrom (free to distribute). I'm attaching both as a zip as GitHub doesn't allow other file extensions:
When loading this movie into BizHawk with a different bootrom loaded, BizHawk will just attempt to replay it and it will desync. It should give some sort of warning.
This is happening on Fedora but I believe @CasualPokePlayer reproduced it on Windows.

Research direction
Start by loading the attached bizhawk_sml_movie.zip in BizHawk with a different Sameboy bootrom, first reproducing the desync described in the issue. Trace the movie-loading and playback path to determine where the recorded firmware is available for comparison; done means a mismatch produces a warning or error before playback proceeds.
