The GBA Net Boot is a wireless tool that allows you to receive and boot GBA homebrew on your 3DS using its built-in GBA hardware. With GBA Net Send, you can transmit GBA homebrew ROMs from your computer to your 3DS over a wifi network. After receiving your ROM, GBA Net Boot saves it to the SD card and automatically launches open_agb_firm to enable you to run your ROM in native GBA mode on your 3DS. The primary purpose of this tool is to simplify and streamline the process of testing GBA homebrew on official hardware.
Disclaimer
Please note that while this software has been extensively tested without encountering any issues, there is always a chance that it could harm your system, corrupt your data, or result in data loss. Certain aspects of this process, particularly the custom firmware and bootloader, interact with lower levels of the system. It is important to understand that I am not liable for any damage or loss incurred as a result of using this software.
How To Use
Before starting, ensure that you have completed the setup process.
Make sure that the Wi-Fi on your 3DS is enabled and connected, and then open gba-net-boot. If Wi-Fi has not been configured yet, gba-net-boot will wait until your 3DS is connected to Wi-Fi.
Once your 3DS is connected to Wi-Fi, gba-net-boot will wait for you to use the gba-net-send tool to transfer your ROM over the network to your 3DS. The ROM will be saved to the root directory of your SD card as "rom.gba".
After the transfer is complete and your ROM is saved to your SD card, gba-net-boot will automatically launch open_agb_firm. From there, you can navigate to "rom.gba" on the root of your SD card and press the A button to launch it.
Setup
Begin by following the guide to install Luma3DS custom firmware, which will also guide you through the process of installing Boot9strap.
Once you have installed Luma3DS, use OpenFirmInstaller 3DS to install fastboot3DS.
Turn off your 3DS and turn it back on while holding the Home button to access the fastboot3DS menu. Navigate to Boot setup and select Enable FCRAM Boot to enable it. Once you see the check mark, go to Continue boot and press A to proceed.
Optionally, if you want to use the default Luma3DS chainloader instead of GodMode9 3DS, go to Boot setup in the fastboot3DS menu, select Setup [slot 1], and highlight Disable [slot 2] to disable GodMode9. Press B until you reach the main menu, and choose Continue boot. Now, holding the Start button on boot should use the Luma3DS chainloader.
Create a new directory called gba-net-boot in the 3ds directory on your SD card. Copy the gba-net-boot.3dsx file into this directory.
To use gba-net-boot, you must also copy open_agb_firm to your SD card. Place the open_agb_firm.firm file in either the /3ds/gba-net-boot or /luma/payloads directory. If you want to use the Luma3DS chainloader to load open_agb_firm, use the /luma/payloads directory. If you want to set up a slot in fastboot3DS, it doesn't matter which directory you choose. If you want gba-net-boot to use a different open_agb_firm from what Luma3DS or fastboot3DS use, you can copy one version of open_agb_firm into gba-net-boot's directory for it to use and another version in the appropriate directory for Luma3DS or fastboot3DS to use.
Make sure your 3DS has wifi enabled and is connected to the same network as the computer you will be sending your ROM from.
To launch gba-net-boot, go to the 3DS Home Menu and launch the Homebrew Launcher. Find gba-net-boot and launch it. Refer to the other section for instructions on how to use it.
Booting directly into the Homebrew Launcher
To make things more convenient, you can set your 3DS to automatically boot directly into the Homebrew Launcher. This is only possible if you're using Luma3DS v12.0 or later. To enable this feature, hold down the Select button while turning on your 3DS. Once in the Luma3DS configuration menu, navigate to either the Homebrew autoboot or Hbmenu autoboot option, depending on your Luma3DS version. Then select 3DS and press Start to save your changes and continue booting. Your 3DS will skip the 3DS Home Menu and automatically launch the Homebrew Launcher each time you turn it on, until you disable this option by switching it back to Off.
