An unused enemy soldier with a cannon is fully programmed in the game, but never used. He includes full AI, graphics and animations.

Concept Art for A Link to the Past shows Zelda in futuristic attire. The original Legend of Zelda was planned to be set in both the past and the future. This art could be an indication that Nintendo considered reusing the concept for A Link to the Past.

There are several portraits of Mario hanging in houses of Kakiriko Village, pulling on the portraits causes Rupees to come out.

There is a secret room, called the Chris Houlihan room, that is not accessible via normal means. It contains a telepathy tile and 225 Rupees and is used as an error handler if you fall into a hole but the game can't find a proper destination.

This room appeared as a result of Chris Houlihan winning a Nintendo Power contest and being promised an appearance in a Zelda game. Many of the glitches used to access the room were removed in the GBA port though, along with any mention of Chris.

There is an unused item called "The Letter" that occupies the same inventory space as the Magic Mirror. It uses the same sprite as the map, similar to the letter item from the original Legend of Zelda.

Miyamoto had originally planned for "A Link to the Past" to have a party system where you could switch between three characters and utilize their individual abilities. The characters would have been a mix between an elf and a fighter, a magic user, and a girl.

You can use the Magic Mirror to get the Magic Cape early by warping to the area the headstone is in from the Dark World.

The Magic Hammer is called the M.C Hammer in the Japanese release, referencing the American rapper of the same name.

There is an odd glitch that can be used in certain places to allows the player to walk through walls. This makes it possible to beat the entire game in under 3 minutes by simply walking to the end room with the credits.

In the Swamp of Evil, where the Misery Mire dungeon is located, there are three enemies that do not load properly, rendering them invisible. Despite this, they can still attack and take damage, though will remain unseen by the player.

These invisible enemies are Ku, some of which can be seen in the Swamp of Evil. The ones that do load properly are positioned in the deep water of the swamp, while the invisible ones are located in shallow water. It's likely the enemies were only programmed to function in deep water, and thus either the terrain was different during development, or the enemies were simply misplaced.

After Ganon has been defeated and the staircase to the Triforce has appeared at the end of the game, it is still possible to fall down the pits surrounding the arena. This will reset the boss battle, and the player will have to start the fight over from the beginning once they re-enter the pyramid, just like if they had fallen in the pit during the fight.

It is possible to deflect Agahnim's magical projectiles using the Bug-Catching Net. While the timing is trickier than using the sword, the circular swing of the Bug-Catching net can also protect Link from the cluster projectile that scatters on being hit.

In the western release's instruction manual, Ganondorf is addressed by the full name "Ganondorf Dragmire", while Ganon is addressed by the alias "Mandrag Ganon", which means "Ganon of the Enchanted Thieves". This was the result of Nintendo of America's translation team wanting to make their own contribution to the story. While these names do not appear in any game in the series, Ganondorf Dragmire has been used in Western promotional materials as recently as 2017.

There is a boomerang glitch that can be performed in Kakariko Village that causes Link to not catch the boomerang, but causes the boomerang to go across the screen repeatedly. This can be done in both the SNES and GBA versions

The catfish in the Swamp of Ill Omen that gives Link the earthquake medallion is based on 18th century Japanese folklore. Namazu is a catfish that would wiggle its body in the water and bring chaos and destruction to the land. The skull shaped stones found on the screen to throw in the circle of stones represents the stone used by Kashima to pin Namazu down and the circle of stones around Namazu represents Namazu's prison (since stones do not float, what the player sees is the top of stones that go to the lake's bottom).

In Kakariko Village, the player can enter the house of a blue dressed woman located at the northwest part of village. Inside, the player can find a Cucco underneath one of the pots. The player can sprinkle some Magic Powder onto the cucco, and it will transform into a woman. This humanoid version of the Cucco explains that it is the Weathercock in the center of village that watches Link harass the Cuccos. This means the Weathercock is responsible for sending Cucco's to attack Link if Link harasses a Cucco. She also tells Link that the human shape is uncomfortable for her.

During a Q&A on Nintendo of America's official Twitter account, CEO Reggie Fils-Aime revealed that The Legend of Zelda: A Link to the Past is his all-time favorite game.

The Japanese release of the game was titled "Legend of Zelda: Triforce of Gods". The name was changed for the Western versions of the game for religious reasons.

If Link goes to the Master Sword pedestal before rescuing Zelda from the prison cell at the beginning of the game, he'll encounter a glitched enemy that resembles a bouncing head of a villager from Kakariko Village. The Master Sword is also not in its pedestal.

If Link possesses a red shield and the Ether medallion, Link can obtain an "ice" shield that has a blue palette swap in place of the usual red color on the shield. Link must use Ether while a Pinket takes Link's shield and then kill the Pinket afterwards. When Link picks the shield back up, it will turn blue. Using Ether again will return the shield to it's original red color.
