Unused Bosses

There are two unused bosses that would have presumably been used on the fire and underground level of the castle, which are the only two castle levels without a boss at the end.

Easter Egg

While walking through the corridor to the princess after beating the last boss of the game, the Red Dragon, press and hold A + B + Select + Start + Up + Left on Controller 1. The princess, surprisingly, meets you topless.

You can't see the topless princess in the Sprite Viewer of the Test Menu, though. But, even dressed, the Princess sprite itself consists of two parts, the nude top (which even has a couple of animation frames, better seen in motion) and the dress, which covers the nudity. When the cheat is used, the top part of the dress is simply removed.
