dll?

[arrowsmith5]

I was wondering if someone could show me a tutorial or could tell me how to make dll files for an injector?

You first need to learn a programming language, preferably C++.

Start learning HERE

Once you know what you're doing, take a look in the Project Blackout Source Code section HERE

Lol, those are essentially the 'hacks'. You don't make them that easy, I suggest you download a few and use them at first.
If you have your mind set on making hacks, though, start learning the language C++
