Appendix:Emerald walkthrough/Section 3

Rustboro City

Devon Corporation

Now that you have reclaimed the Devon Goods, head back to the Devon Corporation building in Rustboro's northwest corner. The grateful Devon researcher is waiting on the city's east side, and hands you a Great Ball before escorting you inside to meet his boss.

On the third floor, the company president introduces himself as Mr. Stone. He thanks you for reclaiming the stolen parts, then asks for another favor. He doesn't expect you to work for free, of course, and rewards you with your very own PokéNav! In return, he asks that you deliver a Letter to a man named Steven in Dewford Town. To reach Dewford, you will need to cross the sea, so Mr. Stone suggests booking passage with Mr. Briney, the friendly old sailor from Route 104.

As you leave, take note of the Scientists on the second floor. None of them are having much luck with their projects, except one, who has developed a device that can resurrect ancient Pokémon from Fossils.


The PokéNav is a small, electronic device produced by Devon Corporation under the orders of Mr. Stone, who wanted a way to keep track of a Pokémon's feelings. It has four different functions, though only Map and Condition are available at first.

  • The Map page displays a map of Hoenn, along with the user's current location. It's also possible to zoom in to see a basic layout of towns and cities.
  • The Condition page shows a Pokémon's five Contest stats in detail. It can be used to search for party Pokémon, or all owned Pokémon at once.
  • The Match Call function records data of up to 85 people, including non-Trainers like Mom and Professor Birch, and allows the user to call anyone who has registered their PokéNav with the user. This will also alert the user when any registered Trainer, including Gym Leaders, want a rematch. Only the first four rematches with each Trainer will see their Pokémon rise in level and evolve, though there is no limit on the number of times these Trainers may be rebattled. After entering the Hall of Fame, each Gym Leader will offer a rematch as a Double Battle.
There are several people whom you have already encountered, that you must seek out and speak with in order to register them:
  • The Ribbons page displays all Ribbons the user's Pokémon have acquired. Though hidden initially, this function unlocks when any of the user's Pokémon gains a Ribbon.

When you leave the building, you are stopped by one of the Devon Scientists. He adds the Match Call function to your new PokéNav, and asks that you call Mr. Stone as a tutorial.

Rival Battle 2 (optional)

May/Brendan is waiting for you just outside the Poké Mart. She/He notices the Match Call feature on your new PokéNav, and each Trainer registers the other. Your friend mentions passing Mr. Briney in Petalburg Woods, before asking about your Pokédex and challenging you to a battle.

Routes 105 and 106

Route 105

As the voyage is a quick one, there is no time to fully explore the waters of Routes 105 and 106 just yet. Return after earning the fifth Badge in order to travel at your own speed.

Checking In

As you sail with Mr. Briney through Route 105, you receive a call on your PokéNav. It's Dad; he heard from Mr. Stone about you getting the device and just wanted to check in. After the brief conversation, the ship makes landfall in Dewford Town.

Dewford Town

Dewford Town

Dewford Town is a tiny island town in the southern ocean. Despite its isolation, many Trainers visit the area to challenge the Dewford Gym.

Dewford Hall

Located to the north of the Pokémon Center, Dewford Hall is known as "Everyone's Information Exchange". Though Dewford is a tiny island community, when someone coins a trendy phrase here, it quickly spreads throughout the region. Speak to the boy outside the building to learn the coolest thing in cool right now; if you disagree, he offers a chance to change the current phrase, which the residents inside will quickly adopt.

Hook the Big One!

Speak to the Fisherman outside the Gym, and answer his question to receive the Old Rod. This low-end fishing rod can hook Pokémon from almost any body of water, so be sure to try it out everywhere!

Dewford Gym

Dewford Gym

Dewford Town Pokémon Gym
Leader: Brawly

A big wave in fighting!

The Dewford Gym specializes in Fighting-type Pokémon. Flying- and Psychic-type moves are the most useful here, so this is a great opportunity to train a Taillow, Wingull, or Ralts. Keep your Normal-, Rock-, Steel-, and Dark-type Pokémon out of the fray for now. The Gym is dimly lit when you first enter, but the building lights up bit by bit for each Gym Trainer you defeat. Once the Gym Leader is defeated, the entire Gym lights up completely.

Even with only three Pokémon, Brawly can be a tough opponent. Both his Machop and Makuhita have the Guts Ability, which boosts the Pokémon's Attack by 50% when afflicted by a non-volatile status condition. Meditite can use Reflect and Light Screen to boost his team's Defense and Special Defense, respectively, and its Focus Punch is dangerous if you ever let Meditite go an entire turn without taking a hit. Bulk Up allows all three to raise their Attack and Defense.

Dewford Gym

After the battle, Brawly awards you the Knuckle Badge, which ensures obedience of all Pokémon up to level 30 and enables the use of Flash in the field. He also hands out TM08 (Bulk Up) as a prize, and registers himself in your PokéNav.

Route 106

Route 106

Until you earn the fifth Badge, you cannot fully explore the waters of Route 106. Battle the trainers on the beach for now.

Granite Cave

Granite Cave, 1F (Entrance)
Granite Cave, B1F
Granite Cave, B2F
Granite Cave, 1F (Back)

While the ground floor of Granite Cave is well-lit from the natural light outside, it can be difficult to explore the underground portion without the use of Flash.


Speak to the Hiker near the entrance to receive HM05 (Flash). Head west to find an Escape Rope, then climb down the ladder to B1F.


Go northeast until you reach a muddy slope, then collect the Poké Ball from the dead-end tunnel to the south. Continue moving to the southeast and take the ladder down to B2F.


Head southwest to a group of cracked rocks, then climb onto the upper level. Turn northeast and inspect the rock on the center platform for a hidden Everstone before taking the ladder back up to B1F.


Climb the next ladder back up to the north side of 1F.


Follow the tunnel all the way to the west, then turn south to reach an isolated chamber.

1F (Back)

In the rear chamber, you find Steven researching rare stones. Give him the Letter from Mr. Stone to complete your mission, and Steven gives you the TM for his favorite move, Steel Wing, in return.

Dewford Town

Mr. Stone still needs you to deliver the Devon Goods to Captain Stern. Talk to Mr. Briney on the pier to inform him of your successful delivery, and the two of you, along with Peeko, set sail at once. Sail directly to Slateport City, or briefly backtrack to receive thanks for delivering the Letter.

Rustboro City (optional)

You can now return to Rustboro City to receive an Exp. Share from Mr. Stone at Devon Corporation.

Routes 107 and 108

Route 107
Route 108

Like with Routes 105 and 106, there's no time to fully explore the area at the moment.

Route 109

Route 109

The sprawling beach of Route 109 is packed with Trainers who aren't just here to work on their tans. Scour the sands for hidden items before heading north to Slateport City.

Seashore House

The hut on the beach's west side is known as the Seashore House, where refreshments are sold to thirsty beachgoers. Defeat all three Trainers inside, then speak to the proprietor. He rewards your effort with a free six-pack of Soda Pop! From this point on, you can also buy individual bottles at  300 apiece.
