C# hacks

Moreover, you have to understand what you're doing.
I've seen a lot of people writing on addresses but not even knowing what they're, what they're doing and why do the modification enable you to cheat3

Thats what i mean with follow tutorials ^^

If you really want to get started with hacking, first you need to start with programming. Since you're in the C# thread, I'll recommend Head First C# by O'Reilly Media. It's a book, you can get digital copies of it online though. Otherwise, look at some tuts online and start questioning everything. Use MSDN forums for just general programming. Once you're up to speed with just general coding, then you can start looking into editing memory addresses using offsets and the suchlike, which is what basic memory hacking involves. From there you should be able to find your own way :P

ty bro ^_^

learning coding by reading books is like learning how to sex watching porn

it's a no-no

I'd have to agree with you, however, the book that I mentioned is not just theory. Every single concept gets introduced, an example is given, and then you must solve at least one task using it. It will then also come up again later in another task. Honestly, to call it a book would be like calling an interview a chat :3

you both are awesome your comments made me laugh for a minute or so
