I've been browsing around GBATemp.net and Wololo.net for some time now, but I just don't understand some things people are talking about in the hacking scene. Like: What's CEF? What's Open CMA? What's PRO? What's TN? All those things. Could someone please make things clear, by, for instance, creating a post or something with all things and terms explained to beginners? That'd be great because things would be much more understandable.
