Continuity mistake: The game begins and ends in the same room, with the sleeping princess Zelda. There is a difference though: in the beginning she is on a bed sided by 2 braziers, which are gone in the ending - that's because they are an addition for the NES version. The 'in-game' version of the room was extended with columns all the way, and added those braziers. The ending loads the original Famicom Disk System version of the room, without them.
