This is a skin-changer I've been using for a long time, it has been undetected since 2014 (Duh, it's private.) And I figured releasing it for the sake of the community. (Auto-updates after every update, no need to update.)
Pretty straightforward to use:
In config you change the ID(s) for what skin you want in settings. (You get the skin ID(s) in the Skin ID wordpad added.)
For knives there are differnet models 5 being M9 and 4 being karambit, etc.
Second just run JLoad and launch CS:GO (If crashes try again.)
