There are many places where the boulders triggers do not activate properly. Maybe due to the hit box placement or mario's speed/positioning it fails many times to trigger.
This can be found in the boulders puzzle to get one of the fuses where one bolder doesn't reset when he falls on the slope after falling into the hole to return to the door.
It also happens after the skater fight where he doesn't trigger the boulders easily and one of them is essential to unblock the path to progress.
save file after the skater fight to test:

Possible solutions:
search for all boulder triggers and increase the associated boxes (can cause issues with Lara)
tweak the Mario positioning obtained from libSM64 (can cause issues with portal transitions)
tweak the trigger evaluation when it involves boulders to more easily activate them.
Current workaround:
Try to walk around and stop several times over the trigger floors until it eventually triggers (sometimes crawling helps).
Try to crawl around the boulder when possible.
