NTR CFW Plugins:About
NTR CFW is a custom firmware for 3DS made by 44670 also known as Cell9.
It features an ingame menu and a plugin loader. The plugin loader will allows you to start and attach a program of your creation into a process when it'll start. That will permit you various things, especially cheats and others data manipulation like bots, dump etc.
This wiki is based around documenting these things and what they do, as well as cheats and romhacks. To start developing a plugin, I recommend visiting these github projects: NTRClient: NTR Server/Debugger by 44670 Hello World Example Plugin by 44670
