You really don't require a special injector or something.

A tip for you guys :
When downloading hacks, if there's a injector included, do not use it. People usually bind keyloggers and stuff into the injector.
So the best and safest way to use hacks is find a trusted injector, and use that to inject any dll to all of your games.

My personal favourite is the classical PerX injector, simple and easy to use.
