This is just a template for anyone who wants to get started on text-based 3DS homebrew, and doesn't care about it looking good. It is the bare minimum for running an app, but notes are included. It is of no use to people who don't want develop apps. Download How to use You need some basic knowledge of C of course, but I've included some notes in the code. Here are some commands: make: build a 3dsx (NINJHAX) and cia (Gateway) executable. make clean: delete the previously built files. make run: Runs the homebrew file in 3dmoo so you can at least know if it works. How to make it look nicer Using printf is easy, but it's not pretty. Using colors can change that. I made a file to easily do just that. Save this as color.h in the source folder. Add #include "color.h" to the top of your source file. Use SET_COLOR(x) whenever you want to switch the font/background color, where x is any one of the colors listed in color.h PS: I'm aware that another Hello World app exists, but it is far more complex and uses a custom font.
