Installing Unlaunch
You are about to install Unlaunch, a permanent bootcode exploit which gets installed onto the DSi console itself, allowing full control of the console on boot, and as a result, allows homebrew applications full access to the hardware without restrictions from DSi system apps or DSiWare titles.
DANGER
If you have not yet done so, please follow Dumping NAND. A NAND backup + ntrboot (or a hardmod, provided you know how to solder) would allow you to restore this backup in case the console gets bricked afterwards.
DANGER
Installing or uninstalling Unlaunch, while safe, writes to the console's NAND, so there's a small chance to brick your console!
WARNING
If you do not have access to a PC, or if your PC is running ChromeOS, then please do not install Unlaunch. A PC (running Windows, Linux, or macOS) is required to ensure the SD Card used is formatted in a way compatible with Unlaunch.
WARNING
Unlaunch is not compatible with Nintendo DSi development consoles.
