All ROM Hacks Are Verified to Be Pokemon Emerald-Based

20 Best Pokemon Emerald ROM Hacks

Here are our picks for the best Pokemon Emerald ROM hacks to play this year, ranked in reverse order.

Keep in mind that this list is based on our own experience, so you may have a different opinion, especially when it comes to the top five. Regardless, we hope this ranking helps you discover your next Pokemon adventure.

20. Pokemon Emerald Kaizo

Let’s start our list with a hack that literally has Emerald on the title. Emerald Kaizo is a notorious hack because of its difficulty.

Despite being hard and sometimes unfair, many players still love it.

Players can get all Pokemon from Gen 1 to 3 without the need to trade and that’s a gift if you can withstand the punishing nature of the game.

Notable Features:

• Gym leaders will have 6 Pokemon from the start.
• Cannot use items during battle.
• Challenging Pokemon battles.

19. Pokemon Blazing Emerald

Our next game also has a slight difficulty to it but not at the same level as Pokemon Emerald Kaizo.

We’re talking about Pokemon Blazing Emerald which is still Emerald with some features added.

The difficulty spike is there and you have three different starter Pokemon here which are Clefairy, Eevee, and Pikachu. That alone gives you a challenge and the mechanics have been updated to the later generations.

Fairy-type is available as well as added moves and abilities. The story is still the same and the challenge stems from the combat, for the most part.

Notable Features:

• Pokemon trainers and gym leaders have changed Pokemon.
• Day and night cycle.
• Physical and special split.

18. Pokemon Theta Emerald EX

Number 8 is Pokemon Theta Emerald EX. Before we continue, there are other versions of this hack with Pokemon Theta Emerald being the original game or hack.

There is another version of Pokemon Theta Emerald Renev but we will put EX above all of them. It is the best version out of the others and they’re pretty much the same hacks with some slight differences.

This hack prides itself on having over 700 Pokemon from different generations, 600 moves, 100 abilities, and even Mega Evolution. It also includes Primal Reversion and Fairy-type.

Notable Features:

• Level cap is 250.
• TMs are reusable.
• Physical and special split.

17. Pokemon Ephemerald

Pokemon Ephemerald is still pretty much Pokemon Emerald. It has the same story and some of the base features.

The main gimmick or hook of this ROM hack is that there are Pokemon with different looks. These are called Sapphorosian Forms, where two Pokemon are combined to make them look a bit different.

That’s a trend nowadays with some hacks and fan-made games where they have fused Pokemon to use. That’s an interesting feature since it throws a wrench into your standard Emerald experience.

You’ll have some fun tackling and playing with the new Pokemon available for you to use.

Notable Features:

• Around 300+ Pokemon up to Gen 3 (Fused).
• Pokemon have changed stats, types, and more.
• Optional boss fights.

16. Pokemon Mega Emerald X and Y Edition

Pokemon Mega Emerald X and Y Edition is Pokemon Emerald but with a Gen 6 coat of paint. The story is still the same but the main allure here is that you start off with Gen 6 Pokemon.

That’s why the name is X and Y edition because those games were released for the Nintendo 3DS which introduced Gen 6.

Another addition is that you can explore 2 added Regions, Kanto and Kalos. Mega Evolutions and Primal Pokemon are also added.

The roster goes up to Gen 6 with new Moves and more.

Notable Features:

• Pokemon goes up to Gen 6.
• No need to trade evolve a Pokemon.
• Dual battles.

15. Pokemon Emerald Crest

There are two big hooks for this hack, number one is that the Pokemon roster goes up to Gen 8, although not all are available.

The second hook is that there are a lot of forms like Alolan, Galarian, and even Hisuian which only appeared in the Legends Areceus game.

It has the same story as Pokemon Emerald with a ton of features to boot. You get things like a Teleport system, Mega Evolution, auto-run, and more.

Notable Features:

• Roster goes up to Gen 8.
• Questing system.
• Physical and special split.

14. Pokemon Emerald Rogue

Emerald Rogue utilizes a lot of the features from Emerald but the gameplay varies for this game. This is a ROGUE-LIKE game that involves strategy but still uses turn-based combat from the Pokemon series.

You start at a hub and choose the path on which way you go. This continues until you get every Badge and progress the game.

The story doesn’t have much weight and it all involves random elements like which Trainer you encounter. Even if you fail, all the Pokemon and items you get are retained.

Get stronger and conquer the game to finish it.

Notable Features:

• Character customization.
• Mega Evolution.
• Adjust the game’s settings anytime.

13. Pokemon Team Rocket Edition: Dragonsden Version

If you want to experience playing as a bad guy in a ROM hack, one of the best options around is Pokemon Team Rocket Edition: Dragonsden Version, where you can witness the events of the FireRed/LeafGreen story from the perspective of a Team Rocket member.

This hack has around 70 hours of gameplay, and you need to work your way up through the organization’s hierarchical system. As you complete missions, your reputation within Team Rocket will grow, and your uniform can change depending on your rank.

The Dragonsden version also includes optional events, side quests, and brand-new areas that weren’t available in the original Pokemon Emerald, giving you even more content to explore beyond the main story.

Notable Features:

• Replaceable HMs and unlimited TMs.
• Pokemon roster, moves, and items from up to Generation 8.
• Built-in EV training mechanic.

12. Pokemon Too Many Types

As the name suggests, this Emerald-based ROM hack features unique gameplay where you can explore various types of Pokemon, way above the normal number that you can see from the core series.

With newly invented types like Magic, Obsidian, Fear, Sand, and Sonic, Pokemon Too Many Types will surely challenge your preconception of modern Pokemon battles, as you need to memorize their strengths and weaknesses.

If you’ve already finished this hack, you can even try its sequel, Pokemon Too Many Types 2, adding 80 more types to the game and a variety of story-related content that makes it a lot more different from the original Emerald.

Notable Features:

• 44 new Pokemon types.
• Added 118 new moves.
• Revamped National Dex consisting of 295 additional Pokemon.

11. Pokemon Seaglass

Pokemon Seaglass delivers a Pokemon Emerald experience through the lens of Game Boy Color graphics. The visuals bring a hint of nostalgia of classic Pokemon games, but in a much more colorful way.

In addition to its cozy-inspired visual overhaul, Pokemon Seaglass introduces several improvements to the original game, including new minigames, expanded landmarks in cities like Rustboro, and a Hard Mode for players looking for an extra challenge.

Compared to many other ROM hacks on this list, Pokemon Seaglass features a smaller Pokedex. However, it makes up for it by adding cross-generation evolutions for several Pokemon species.

Notable Features:

• More relaxed, GBC-style graphics.
• Buffs to some underrated Pokemon like Noctowl, Sceptile, and Octillery.
• Following Pokemon.

This unique crossover offers a fresh adventure while retaining the core gameplay that made Pokemon Emerald a classic.

Super Mariomon features its own fan-made region and a completely original roster of Mariomon. While the setting and creatures are entirely new, the gameplay stays true to the classic Pokemon formula, with familiar mechanics like capturing, training, battling, and type matchups.

Notable Features:

• 150 capturable Mariomons.
• Better visuals compared to vanilla Emerald, reminiscent of the places in the Super Mario games.

9. Pokemon Emerald Imperium

Did you enjoy playing Pokemon Radical Red? You should give this hack a try if you want to challenge yourself a bit more when it comes to winning Pokemon battles.

Inspired by the success of Pokemon Radical Red, Pokemon Emerald Imperium was designed to offer a much more punishing version of the original Pokemon Emerald while expanding the Pokedex to include Pokemon from Generations 1 through 9.

Mega Evolution is also present in Pokemon Emerald Imperium, as well as some species having their Gigantamax forms.

Notable Features:

• A more difficult Hoenn League experience.
• Level caps.
• Better decision-making for AI Trainers during battles.

8. Pokemon Lazarus

Although it’s built on Pokemon Emerald, Pokemon Lazarus feels like an entirely new game. It features a brand-new region, an original story, new starter Pokemon, side quests, and plenty of additional content that sets it apart from most hacks.

The lore of Pokemon Lazarus is set in the Ilios region, a place inspired by parts of mainland Greece and their surrounding islands. The game hosts around 400 Pokemon, including several species from Generation 9.

Pokemon Lazarus is also equipped with GBC-style graphics similar to Pokemon Seaglass, and you’ll get to choose one from nine starter Pokemon instead of three.

You can further immerse yourself in the hack by playing its side stories containing quests that you can complete for hours. Some features in the hack are also there to help you focus more on the story rather than just grinding your Pokemon for levels.

• New region and story to explore.

6. Pokemon ROWE

Pokemon ROWE is described by its creator as an “open-world version of Pokemon Emerald,” and it lives up to that description.

From the moment you begin your adventure, you’re free to explore nearly every part of the Hoenn region without the usual story progression or NPC roadblocks. You can even challenge the gym leaders in any order, giving you the freedom to shape your own journey.

You’re starting out to be a Trainer and be the best there is but mysteries and the occasional appearance of the villainous Team Mirage to hinder you on your journey.

With the hack’s new story comes a number of new characters, such as a Pokemon professor, male and female protagonists, and other relevant NPCs.

Notable Features:

• Newly remapped Hoenn.
• 200 Fakemon
• New characters, moves, and abilities.

The villains take advantage of you and fund your experiments but not for good. You realize this and now you have to rectify your mistakes. Gather your Pokemon and take down this villainous organization. 

Fairy-type and updated stats are also included in this hack. Mega Power also has some nice sprites and graphics going for it.
