If you don't want to compile yourself but you still want to get the latest build, please use our TWLBot github repository

In order to compile this application on your own, you will need devkitPro with the devkitARM toolchain, plus the necessary tools and libraries. devkitPro includes dkp-pacman for easy installation of all components:

 $ dkp-pacman -Syu devkitARM general-tools dstools ndstool libnds libfat-nds

Once everything is downloaded and installed, git clone this repository, navigate to the folder in which it was cloned, and run make to compile the application. If there is an error, let us know.

Custom Fonts

GodMode9i uses the same FRF font files as GodMode9. To create an FRF font use GodMode9's Python script or you can find some in the resources/fonts folder in this repository.

When loading GodMode9i will try to load /gm9i/font.frf on your SD card and if that fails will load the default font. To change the default font when building GodMode9i, replace data/font_default.frf with your font.
