Q&A

Is that final empty spot in your FireRed Pokédex taunting you? That spot belongs to Mew, and unfortunately, there is no longer a way to catch one legitimately, as Mew was an event Pokémon only distributed during Nintendo events. The only way to get Mew these days is to trade, to use an Action Replay code, or to use a FireRed randomizer ROM. Keep reading to learn more.

Ways to Get Mew in Pokémon FireRed

If you have a physical copy of FireRed, try trading with someone else to get a legit copy of Mew.
Use an Action Replay code in an emulator (or on your actual Action Replay) to spawn a Mew.
Use a randomized FireRed ROM to potentially find a Mew out in the wild.

Method 1 of 3:

Trading for Mew

Download Article

1
Find a friend with Mew. Trading for Mew is the only legitimate way to obtain a Mew in FireRed anymore. Mew was an Event Pokémon and was only available during a single event in 2006.
- There is a glitch that people claim will work to find Mew, but this only works in the original Pokémon games. It does not work in FireRed.
2
Build up good trade stock. Mew is exceedingly rare, and your friend won't likely give it up easily. You'll need to sweeten the pot, so ensure that you have a good selection and be prepared to part with multiple top-tier Pokémon to get it.
- Any of the Legendaries make for good trade stock. This includes Articuno, Zapdos, Moltres, Raikou, Entei, and Suicune. Also, if you have some of the other past event Legendaries, such as Lugia and Ho-oh, these will make your trade much easier.
- Mewtwo will most likely need to be traded in order for your Mew trade to happen.
- EV-train your trade stock. A group of Pokémon that have been expertly EV-trained will command a much better trade value than freshly-caught Pokémon. Invest some time in building up your team before you start the trade.

Using Action Replay Codes

Visual Boy Advance is the easiest emulator to use and enter Action Replay codes for. If you have an actual Action Replay, use this guide to enter the codes listed in this section.^{[3]

2
Save your game using the emulator. Emulators allow you to take "snapshots" of your game so that you can quickly return to it later. This acts differently from saving in the game itself, and will allow you to roll back in case the code doesn't work. If you're using VBA, click File → Save and then select an empty slot.^{[4]

- There is a chance that you will get a Bad Egg instead of Mew, which will break the game. You will need to load this save file if that occurs. Loading the file will revert the code and rescue your game.
This will open the Cheat list window, allowing you to enter cheats.^{[5]

Gameshark.... Even though you're entering an Action Replay code, you'll be using the Gameshark code tool.

Enter "Mew" into the Description field and copy the following code into the Code field. Click OK after pasting the following code:^{[6]

With the code above enabled, Mew should be the first Pokémon that you encounter. It will be around the same level as the other wild Pokémon in the area.
You'll need to capture Mew like you would any other Pokémon. Lower Mew's health to increase the chances that you'll catch it when you throw a Poké Ball.
After you're finished creating Mews, return to the Cheat list window and disable the codes to return your game to normal.

Method 3

Method 3 of 3:

Use a Randomizer ROM

1
Download a randomized FireRed ROM. You can either choose to download a pre-randomized ROM, or you can download your own randomizer. A randomizer is a tool that scrambles up the Pokémon you can find in a given Pokémon game.^{[7]

- Never download a ROM that you don't trust.
Note that a randomizer doesn't guarantee your chances of finding a Mew, but it allows Mew to be one of the Pokémon switched out for a different Pokémon. If you want a Mew for sure, it's best to use an Action Replay code. However, if you like the thrill of not knowing if you'll find a Mew, playing through a randomized version of FireRed would be a fun challenge.

Question

How can I obtain a shiny Kanto starter from Professor Sycamore in Pokémon X and Y?

M is your new overlord

Community Answer

To acquire a shiny Kanto starter, save your game before the cutscene where Professor Sycamore offers you the Pokémon. Choose your starter, then check if it is shiny. If it is not, soft-reset your game by pressing L + R + Start + Select. This method can be time-consuming, but you may find more efficient results with Masuda Method breeding.

Question

Can I still legitimately obtain Mew in Pokémon FireRed, or are other methods available?

Community Answer

Mew was originally distributed as an event Pokémon in 2006. Currently, the only way for you to obtain Mew in Pokémon FireRed is through unofficial means, such as cheating devices.

Question

Can I transfer a Mew obtained using glitches in Pokémon Red or Blue to Pokémon FireRed or LeafGreen?

M is your new overlord

Community Answer

You cannot transfer a Mew obtained from original Pokémon Red or Blue to FireRed or LeafGreen. There is no direct trading compatibility between Generation 1/2 games and Generation 3 games due to fundamental differences in hardware and game data structure.
