RAM hacked to get gTimer/RNG pair.
So Fairy spell can traverse this segment 4 frames faster than non-fairy Link. I checked for other RNG values this early, but nothing came up.
This is what happens if R_2=31 is done. If we can traverse the cave quickly enough, we will get that fairy, but I only succeed by, in this movie, casting Fairy. Assuming that magic I just spent isn't used for anything else, we still need to re-open the menu later. Best done if R_2=72 isn't behaving in some improvement sometime in the future.
