This page is rather stubbly and could use some expansion.
Are you a bad enough dude to rescue this article?

Pokémon Emerald is a greatly-enhanced "third game" to Pokémon Ruby and Sapphire – and as such, contains much of the same unused content.

Sound Test

Sound Test

The Japanese version has a sound test, similar to those in Ruby, Sapphire, FireRed and LeafGreen. Unlike in Ruby and Sapphire, but like FireRed and LeafGreen, it was removed in the localisations. To access it, patch 0x301AC to 21 83 0E 08 in a Japanese Emerald ROM to replace the Options menu (from the Continue/New Game/Options menu after the title screen) with the sound test.

Unused Music

In addition to the unused music in Ruby and Sapphire, Emerald also contains the entire soundtrack from FireRed and LeafGreen, although only a few music tracks from that particular soundtrack are used in Emerald.

Shiny Celebi

Pokemon Emerald Shiny Celebi.gif

For the sake of consistency, every Pokémon in every Pokémon game is given a Shiny variant, and Celebi is no exception. However, because the only way to obtain it legitimately was through distributions, the Shiny version of Celebi was left unobtainable through normal means. This sprite may still be seen (in a lighter hue) if a Shiny Pokémon Transforms into a Celebi.

Unused Maps

Pokémon Festa 2002 Maps

The prototype maps from "Pokémon Festa 2002" are still in the game. However, unlike in Ruby and Sapphire, all the events have been deleted, so there are no people left.

Leftover Aqua Hideout

  • CL:316, 317 and 318 are leftovers from Ruby and Sapphire.

Leftover Contest Hall Maps

  • CL:72, 73, 75, 83, and 84 are leftovers from Ruby and Sapphire.
  • CL:226 to 232 have events data.

Other Leftover Maps

  • CL:170 to 183 are empty maps with tileset 19.
  • CL:242 is a map without data.
  • CL:312 is a Cave Of Origin map from Ruby and Sapphire.
  • CL:326 is a Seafloor Cavern map from Ruby and Sapphire.
  • CL:359 is a Battle Frontier map without event data.
  • Map 13.8 is an unused Poké Mart for Lilycove City. However, all of the events have been deleted. Rather than a normal Poké Mart, Lilycove City has the Department Store.

Inaccessible Areas

  • In Map CL:380 which is a Magma Hideout map, the right part is a copy-paste of the left which can only be accessed by cheating.


  • An unused warp is stuck in a wall in Battle Frontier (CL:345) and leads to an unused house (CL:429), there is only a woman without a script inside. That means there must have been a house here.


Warps aren't in the right place and leads to Battle Frontier.

Unused Sprites

  • Unused bunny hopping sprites of the Acro Bike from Ruby and Sapphire are still unused in Emerald and have been retextured.
  • The unused sprite of the sumo guy from Mendel Palace was unused in Ruby and Sapphire and is still in Emerald too.
  • Leftover sprite of a child with glasses in Ruby and Sapphire.

Unused held items

Some Pokémon when found in the wild has a chance of holding an item. But several Pokémon can only obtained via evolution or other means, making catching a Pokémon with these items imposible. Emerald reuses the same list of held items (used or otherwise) from Ruby and Sapphire, and shares many simularaties.

Unused Downpour weather

Another hidden unused rain weather which is never accessible by normal means. A cheat code can be used to enable this weather during a battle by setting the weather value to 2 or 3. This weather has the same effect and animation than the rain (water types moves power multiplied by 1.5 and fire type moves power halved) but displays an unique message : "The downpour continues.".

Unused Tilesets

To do:
Rip and post them.
  • 16 - Seven corrupted tiles
  • 22 - Only one tile
  • 39 - Early Mossdeep City Gym
  • 57 - Only one tile

Unused Header Names

  • METEOR FALLS (Duplicate)
  • FIREY PATH (Duplicate)
  • JAGGED PASS (Duplicate)
  • SPECIAL AREA (Note: Also known as CELADON DEPT.)
  • All FireRed and LeafGreen HeaderNames

Altering Cave

As with FireRed and LeafGreen, normally only Zubat can be found in this cave, however there are other wild Pokémon that can be found if Mystery Gift is used at an official Nintendo "Wonder Spot". Despite this, no such event has been held in any country. The Pokémon that were supposed to be found were Mareep, Aipom, Pineco, Shuckle, Teddiursa, Houndour, Stantler, and Smeargle.

The plan was probably scrapped because these Pokémon could be obtained by trading with Pokémon Colosseum, Pokémon XD: Gale of Darkness, and/or found in Emerald's extended area of the Safari Zone (except Smeargle, which is found in Artisan Cave instead).

Like in FireRed and LeafGreen, there's also unused text for the Mystery Gift reception of the event-only Pokémon.

Thank you for using the MYSTERY
GIFT System.

There appears to be a rumor about
rare POKéMON sightings.

The sightings reportedly came from

Perhaps it would be worthwhile for
you to investigate this rumor.

Regional Differences

e-Reader support

Similarly to the Japanese FireRed and LeafGreen, the Japanese Emerald contains e-Reader support and its Mystery Gift system (ふしぎなおくりもの, also ふしぎなもらいもの in these games) requires it instead of the Game Boy Advance Wireless Adapter as in the localizations, using a Japan-only Pokémon Emerald Battle-e card set that affects Trainer Hill. Like Ruby and Sapphire, the Japanese Emerald also supports the Mystery Events system (ふしぎなできごと), which requires the e-Reader as well. Overseas, Emerald only supports the Mystery Gift system from FireRed and LeafGreen, although the code for the Mystery Events is still present, including the Japanese text.


The Japanese Emerald had a minor audio oversight: the moving Vigoroth at the very beginning of the game incorrectly use Machoke's cry, which was fixed in international releases. These Pokémon were changed from Machoke in Ruby and Sapphire, where they played their correct sound.

Old Sea Map

To do:
Unused dialogue should be here.
The Old Sea Map was an event item that would allow the player to ride on the S.S. Tidal to access Faraway Island and subsequently catch Mew. However, as it was only distributed in
Japan during the Pokemon Festa event in 2005, the item is completely unobtainable outside of Japan, consequently making the translated dialog that occurs during the event, and Mew's unique overworld sprites to be completely unseen overseas without hacking the game.

Mystery Events

Similar to the old woman's house on Seven Island in FireRed and LeafGreen, there is a man in a house in Sootopolis City who would host battles with Mystery Events in the Japanese version, but this was removed from international versions, leaving only the old man (who has a similar message to the old woman's) and the stairs blocked by trees.

Trick House

Careful, you'll lose an eye.
This page or section needs more images.
There's a whole lotta words here, but not enough pictures. Please fix this.

The fourth room of the Trick House (a boulder puzzle) was slightly changed between the Japanese and English versions.

Dive glitch

There's a glitch exclusive to Japanese Emerald where you can use Dive on a dark patch of water inside the Team Aqua hideout after performing a Save & Quit in there. Because the water is not programmed to lead anywhere the game throws you back to Petalburg City. This was fixed in the overseas release by not allowing you to dive in that spot.


In Rustboro City, a young girl named Walda and her parents live between the Pokémon Center and the Devon Corporation building. In the Japanese version, her father says "It is the first time to take care of a child." In the English version, he says "I'm a new father, so raising a child is all new to me." It seems to be an erroneous translation of Japanese 'はじめて' as 'First time' rather than 'New'.
