In my search I not only do I find the last thing within this ROM, but I also use the boss room warp to somehow end up back in Hyrule! I've had a tip-off from MelonSpeedruns who is affiliated with Project 3rd Quest that there's an Easter Egg item hidden within this demo, that involves the Skull Bow and the Fire Arrow technique that was required to progress in the Earth Labyrinth to be used outside the dungeon.
