[SOLVED] How to make own esternal box ESp?

Hey guys I have downloaded a very basic external box esp from here( http://www.mpgh.net/forum/191-call-d...ompatible.html), But it works well.
It is the basic one because I have xp and it appears it is harder/not possible to make amazing external esp hacks on windows xp.

I was wondering what I need to know to make my own?

I want to know what I need to learn, to be able to make my own external esp hack for windows xp. i.e code c++ or something and also what tools I will need.

I'm not suggesting that I will learn 2night and start making one tomorrow as I know that is not possible, but I would like to make one in the future, so the sooner the better.


Thank you
