due to pushes in the nes version being a little more lenient, two problematic boulders were changed into light boulders, at no cost to the intended solution

I knew I saw this cave before! RTA Dash 3 Cave P. :D   
I actually don't know the story on RTA Dash, I see some small differences

Looking at the RTA Dash version, it appears there were a few modifications to the original intention, one of them includes a little "pit" that the first firefly gets stuck in so you don't have to luck push (and the platform the boulder is on is steel instead of brick), and there's no leftside boulder fall.  
  
In short, RTA DAsh deviates from the original bd.nes motif in only those parts.
