Pokemon LeafGreen Version Cheats & Cheat Codes

Pokémon LeafGreen is a remake of the old Game Boy title Pokémon Green, just as Pokémon FireRed is the remake of the game Pokémon Red. If you want to experience these classics, there’s no better way than games like LeafGreen. They update the classics in many important ways. Below, we’ll take a closer look at how LeafGreen works, and what cheats you can enable for it!

Pokémon LeafGreen Summary

Released in 2004, Pokémon LeafGreen is a Generation III remake of Pokémon Green available on Game Boy, now offered on Game Boy Advance and via various emulators ever since. Both LeafGreen and FireRed were particularly successful, becoming some of the top selling games on the Game Boy Advance.

As with most other Pokémon games, LeafGreen and FireRed are essentially the same game with slightly different versions. Depending on which players bought, they got access to special Pokémon and lands to explore. In LeafGreen, there are over 20 Pokémon that players can only get in that version of the game (or through trading with a LeafGreen player).

The update to the game offered many important upgrades that enhanced how LeafGreen is played. These include the ability to play as a female character, a new intro, new lands, and new Pokémon, among much more. The update also allowed for some new methods of enabling cheats, which we’ll get to below.

Pokémon LeafGreen Premise

Cartridge of Pokemon LeafGreen.
Emulators are now a popular way to play LeafGreen.

While Pokémon LeafGreen provides plentiful upgrades to the game from generation I, the story and gameplay retain much of their simplicity. This is a return to the early days of Pokémon in many ways. Professor Oak is here once again to introduce the land of Kanto and teach you about Pokémon. Your primary mission is to visit and beat all Gyms in the land. While you face rivals, there’s relatively little overarching story, just a lot of exploration, collection, and battles. However, Team Rocket shows up to thwart you at every turn, so your character needs to stay on their toes.

The mechanics will also seem very familiar to anyone with some experience in Pokémon games. You play from an overhead perspective, moving your character through a world filled with secrets and Pokémon. Successfully capturing Pokémon allows you to raise them, evolve them, and use them in turn-based battles with others. LeafGreen added a number of different advancements to combat, including a plethora of new types and other features that add complexity.

Once players beat the primary story in Kanto, they gain access to the Sevii Islands, a new area filled with unique challenges and extra-special Pokémon.

The game also supports the ability to connect to other players with the Game Link or wirelessly with the Game Boy Advance adapter. That allows for competitive multiplayer and trading.

Pokémon LeafGreen Main Characters

As one of the earlier Pokémon games, Pokémon LeafGreen features quite a few familiar faces. You can expect to run into people like:

Professor Oak: Oak is a famous Pokémon researcher who knows just about everything there is about the creatures and where to find them. He introduces the player’s character to Pokémon and helps teach how to capture and train Pokémon, as well as use the Pokédex. Once the character is ready, Oak sends them on their way to visit Pokémon Gym and battle their leaders.

Team Rocket: Most Pokémon trainers are grouped up by teams, but Team Rocket is special…in an evil sort of way. They’ll do anything for power and have an eye for rare Pokémon. That means they’re involved in a lot of schemes to steal, capture, and abuse Pokémon, which the player character must foil. This time around, they’re led by by Giovanni.

Brock: Brock is the leader of a nearby Gym when the player character first starts their journey. While he’s far from the only Gym leader that the character will encounter, he provides an invaluable introduction. Fight his rock-oriented Pokémon and earn valuable prizes so you’ll know what to do next.

Bill: Bill is another Pokémon researcher who studies a variety of Pokémon and is always happy to help a young trainer. The player character should visit his house ASAP to pick up some valuable tips and learn about how to store Pokémon. Oh, and to get him out of trouble.

Mr. Fuji: This old man works hard to care for orphaned Pokémon at his home. He used to be a famous scientist and researcher, but gave it up for the peaceful life. As you can imagine, he detests Team Rocket and will help fight again them.

Elite Four: Once the player character has completed their tour of the gyms in the land and beaten back Team Rocket, there’s one more challenge. The Elite Four are master Pokémon trainers, considered some of the best in the world. Only trainers who’ve won acclaim at every gym can even try to face them. It’s a good idea to study them and learn what Pokémon they use before attempting battle.

Pokémon LeafGreen: Games in the Series

Pokémon LeafGreen is part of the third generation of Pokémon games, which were all released on the Game Boy Advance  throughout the early 2000s. The games Pokémon LeafGreen and FireRed were partnered releases during this time. They were preceded by Pokémon Ruby and Sapphire, and followed by Pokémon Emerald. The fourth generation of games, beginning in 2006, started with Pokémon Diamond and Pearl.

Pokémon LeafGreen Cheats and Codes

Battle in Pokemon LeafGreen.
Battles in LeafGreen can be fun but time-consuming.

Now that you know how everything works, let’s get into the cheats and codes available for Pokémon LeafGreen. Here’s how it all works.

GameShark Codes

The primary method for LeafGreen cheats is the GameShark available for the Game Boy Advance, an additional device that allowed players to input specific codes to enable a variety of cheats. If you want to save time or get all Pokémon at top speed, there’s no better way.

However, there is a small problem with the GameShark. Very few people play on Game Boy Advance anymore. Many use emulators or other ways to play LeafGreen and enjoy one of the classics. Where does that leave cheat codes? Fortunately, it shouldn’t be a problem. Most of the emulators you can use to play Game Boy Advance games on your computer or other device also include a method to enable GameShark. Look in the settings to find a cheats section where you can enable it, or ask the community how to turn on a GameShark, and you should be good to go.

Pokémon LeafGreen Cheats FAQ

Below, we’ll go over some common questions about Pokémon LeafGreen cheats and how they work.

How Do I Know If My Emulator Supports GameShark Abilities?

Pick a reliable, popular emulator with great support, and it shouldn’t be a problem. To start, look up the guide for the emulator and see if it has a section on cheats. Usually, there’s a way to enable specific kinds of cheats in settings. You may be able to turn on a cheat mode, or enable a GameShark mode specifically. In some cases, you’ll need to manually input all your codes in a text box within the emulator to get them working. If that’s the case, label your codes carefully so you know what they do. This also lets you disable them more accurately if you want to.

If you have any additional questions about how to get it working, check the forums. Popular emulators tend to have good communities that will be able to give you quick answers about your GameShark needs.

Can I Still Buy a Physical GameShark If I Have a Game Boy Advance?

Well, they don’t make them anymore, but you should still be able to go old school. Many GameSharks are still sold on eBay, Amazon, and other online sites. The key is getting the right one. They come in several different varieties and kits, depending on what you want. It’s a good idea to double-check the model of your physical Game Boy Advance and find a GameShark that’s specifically defined as working with that model.

I Found a GameShark Code That’s Not Working

That happens. GameShark codes are old and have been shared so often that they can easily get confused. Some may no longer work, some may be for different Pokémon games, and some may be for other devices. The codes we listed above are all guaranteed to work with Pokémon LeafGreen, so if you’re having trouble with one of those, carefully check your input method. Sometimes, you may have to input Master Codes before enabling additional cheats. Stay patient, do a little research, and you should find a way to get the cheat you want.

My Mewtwo Cheat Isn’t Working!

Mewtwo is a special case when tracking down legendary Pokémon. You need to enable the Time Machine to gain access to its special area. Otherwise, the teleporting cheat may not work in this case, even if it works for your other legendary Pokémon.
