Health and Safety Information is a built-in (stock) app that comes pre-installed on all 3DSs. It is intended to warn the user about some health risks when using the device, such as seizures. The app is split into two sections: “Important Info” (which attempts to discourage the user from installing CFW), and “Health and Safety” (which tells about the health risks of using the device and 3D). You can inject any homebrew app (like FBI) into Health and Safety Information, as long as the app is not bigger than the original Health and Safety app. You inject homebrew into H&S (short for Health and Safety) using GodMode9.
