Where to Start?

I was wondering, if i want to make Game Enhancements, or hacks, or whatever you want to call them, Where should i start?

I have a proficient knowledge of Visual Basic, and i'm somewhat along on C++ i know the basics, and am still learning.

But i'm having trouble grasping the concept on What to do, when making a Game "Hack". i have no knowledge on how they work.. or how it is made.. could somebody point me in the right direction, i would really like to learn, so i could make, and update my own, for reasons being, i wouldn't have to wait for hacks to be updated when they are down, and two, i hate to feel like a "Leecher" whenever i download "Hacks", without ever contributing to anything, basically, just take, and leave.. so, if anybody could tell me, or if there are any tutorials, text, or video.. point me in the right direction to learn



EDIT: I Also already know Basics of ASM (Assembly Language), primarily, jumps, push, esi, ezi, things like that.. I cracked a program once, it took all day.. and gave me a headache.. so i gave up on that.. but i still know some ASM

I need to start a 'if you want to learn hacking' thread next to the 'if you want to learn C++' on so we can get these repetitive questions over with, haha. It's simple really, find as many tutorials an examples as you can, all over here and google, for C++, Assembly and start with like 'how to hack pinball,' and crap. Good luck.
