• ² If you intend to use the hblauncher and fbi targets ensure you have set IP3DS in the Makefile to the ip address of your 3ds on your network.
• In homebrew launcher press Y and you can netload your 3dsx file.
• In FBI go to remote install and select Receive URLs over the network.
• ³ This requires having makerom and bannertool both included in buildtools as 7z files.

4. Ensure you have the environment variables plugin installed (in linux you can install this by installing the codeblocks-contrib package)
5. Choose Settings > Environment and scroll down to the Environment Variables section.
6. Add DEVKITPRO to point to where devkitpro is installed

Compiling

Unix

You will need devkitArm which can be obtained with

wget http://sourceforge.net/projects/devkitpro/files/Automated%20Installer/devkitARMupdate.pl
chmod +x devkitARMupdate.pl
sudo ./devkitARMupdate.pl /opt/devkitPro
echo "export DEVKITPRO=/opt/devkitPro" >> ~/.bashrc
echo "export DEVKITARM=\$DEVKITPRO/devkitARM" >> ~/.bashrc
echo "export PATH=\$PATH:\$DEVKITARM/bin" >> ~/.bashrc
source ~/.bashrc

Please note: The env variables need to be available from sudo

Defaults env_keep += "DEVKITPRO DEVKITARM"

Windows

Install the following using devkitProUpdater:

• devkitArm
• libctru
• citro3D

Note: It is suggested to install dev tools at the root of your disk drive i.e. C:\Development\3ds-homebrew\devkitPro Once installed, make sure you have access to a C compiler from cmd. If you're not sure install mingw-w64 to C:\Development\mingw-w64 and then add the path C:\Development\mingw-w64\mingw32\bin to your env variables. Open command prompt as an administrator and cd into the devkitPro installation folder. Some commands need admin rights to properly install. Additionally make sure your antivirus software does not interfere. Next git clone the latest 3ds_portlibs:

git clone https://github.com/devkitPro/3ds_portlibs.git
cd 3ds_portlibs
make zlib
make install-zlib

Finally, clone this repo and build with one of the commands found in usage.
