Installing Custom Firmware (CFW)

Custom Firmware (CFW) is a modified version of the 3DS’s operating system. It allows you to run unsigned code on your 3DS, which is necessary to install GBA games on the home menu.

There are a few different CFWs available for the 3DS. The most popular ones are Luma3DS and rxTools. Both CFWs have their own advantages and disadvantages, so do some research to figure out which one is right for you.

Once you’ve chosen a CFW, you’ll need to download the latest version and install it on your 3DS. The installation process is slightly different for each CFW, so follow the instructions carefully.

Here are the steps in more detail:

Prepare your SD card. You will need to format your SD card as FAT32. You can do this by using the SD Card Formatter tool from the SD Association.
Create a folder called "luma" on the root of your SD card. This is where you will put the Luma3DS files.
Download the latest version of Luma3DS. Extract the files from the ZIP archive to the "luma" folder on your SD card.
Eject your SD card and insert it into your 3DS. Hold down the L button while you turn on your 3DS. This will boot into the Luma3DS configuration menu.
Use the D-pad to navigate the menu and select "Install Luma3DS." Press the A button to confirm your selection.
Luma3DS will now be installed on your 3DS. Once the installation is complete, you can press the B button to reboot your 3DS.

Your 3DS will now be running CFW. You can now install GBA games on the home menu.

CFW	Advantages	Disadvantages
Luma3DS	– Stable and reliable	– Can be difficult to install
rxTools	– Easy to install	– Less stable than Luma3DS

Preparing the GBA ROMs

To prepare your GBA ROMs for installation on your 3DS home menu, you’ll need to follow these steps:

1. Obtain the GBA ROMs

Start by gathering the GBA ROMs you wish to install. These can be obtained from various sources, but ensure you have the legal right to possess them before proceeding.

2. Convert the GBA ROMs to CIA format

GBA ROMs are typically available in .gba format, while the 3DS requires CIA format for installation on the home menu. You’ll need a conversion tool to transform your GBA ROMs into CIA format. Popular options include gba2cia and NSUI, which are command-line tools that can handle batch conversions.

To convert a single GBA ROM using gba2cia, open a command prompt or terminal and navigate to the directory where both the GBA ROM and gba2cia are located. Enter the following command:

gba2cia input.gba output.cia

Replace “input.gba” with the actual GBA ROM file name and “output.cia” with your desired CIA file name.

For batch conversions, consult the documentation of your chosen conversion tool for specific instructions.

3. Rename the CIA files

Once you have converted your GBA ROMs to CIA format, you’ll need to rename them to match specific naming conventions. The CIA file name should follow this structure:

ROMS_GBA_<Game ID>.cia

Replace “<Game ID>” with the four-character Game ID of the GBA game. You can find the Game ID by searching for the game in a trusted database or using tools like gba2cia with the “-g” flag.

Copying the ROMs to the SD Card

Once you have obtained the ROM files for the GBA games you want to add to your 3DS, you need to copy them to your SD card. This step requires a bit of technical knowledge, but it is relatively simple to perform.

Prepare your SD card: You will need an SD card that is formatted in the FAT32 file system. If your SD card is not already formatted in FAT32, you can format it using your computer’s disk utility program.
Create a folder on your SD card: Once your SD card is formatted, create a folder on the root of the card named "GBA." This folder will store the GBA ROM files.
Copy the ROM files to the GBA folder: Locate the GBA ROM files on your computer and copy them to the GBA folder on your SD card. Make sure that the ROM files are in the .gba or .zip format. If the ROM files are in a different format, you will need to convert them to one of these formats using a ROM conversion tool.

Accessing the Homebrew Menu

To access the Homebrew Menu, you’ll need to use a custom firmware (CFW) that allows for the installation of unsigned code. There are several different CFWs available, but we recommend using Luma3DS. Once you’ve installed a CFW, you can access the Homebrew Menu by holding down the Start button while booting up your 3DS.

The Homebrew Menu is a simple list of applications that you can install and run on your 3DS. To install an application, simply select it from the list and press the A button. You can also use the Homebrew Menu to manage your installed applications, such as updating or uninstalling them.

Installing GBA Games

To install GBA games on your 3DS, you’ll need to use a GBA emulator. There are several different GBA emulators available, but we recommend using the mGBA emulator.

Once you’ve installed an GBA emulator, you can install GBA games by copying them to your SD card. To do this, simply create a folder named “GBA” on your SD card and then copy the GBA ROMs to that folder.

Once you’ve copied the GBA ROMs to your SD card, you can launch the GBA emulator and start playing your games. The GBA emulator will automatically scan your SD card for GBA ROMs and add them to its list of games.

Additional Information

Here are some additional tips for installing GBA games on your 3DS:
