This document details the process of hacking games through the memory. It is aimed towards gamers who want to know how game memory hacking and game trainers work.

1) Running the Game
The game must be currently running in memory for you to hack it. That's why it's called game memory hacking.

2) Getting Out to Windows
Pause the game, and then find a way to get back to the windows desktop. This is accomplished usually by pressing ALT and TAB together.

Some games disable ALT+TAB so your game hacking program should preferably have a built-in hotkey to get out of the game.

Voodoo-card based games running on glide do not support switching out of the game. They will crash if you try to do so. The only way out is to run the game in software-rendering mode, not in hardware-accelerated mode.

3) Running Your Game Hacking Program
You will need a game hacking program to locate hacking information and also to hack the game itself. A trainer can hack games if it already knows the hacking information, but only a game hacking program can locate that hacking information.

Suggested game hacking programs include Cheat Finder, WinHack and Game Trainer. My current choice is Game Trainer 2.0, since it's totally free and very fast.

4) Locating The Memory Address of Important Values
The game stores all the important information that you want to hack, in the memory. Pretend that this memory is a neighbourhood, and all that information each has its own house address.

You are the vandal, the neighborhood bully. What you do is go to an address, and mess things up - ie: hack the game. However, you can't just mess up every address, you might get caught by the police - ie: the game crashes.

So you must know which address to mess up. This is where the game hacking program comes in. It helps you find the address of important information in the game, like your current cash, or the ammo in your rocket launcher.

Different game hacking programs have different ways of finding these addresses, so check your program's documentation for details of doing so.

Locating these addresses is the hardest part of game hacking. You can search for hours and still turn up nothing. That's when you just give up or turn to more sophisticated methods.

5) Hacking Those Addresses
So you now have the address. There are some things you can do with it. Firstly, you can input a new value into the address. For example, you can hack the address so that it contains 50 billion dollars instead of just one hundred dollars.

Or you can freeze the address. This prevents the value in the address from changing whatsoever. For example, you can make your health stay at 100% and it never changes at all. Note that for the freeze to keep on working, the game hacking program (or the trainer) must always be running.

6) That's It
That's it. This is the way that people hack into games. Note that these simplistic methods will probably not work on multiplayer games, as the code for multiplayer games is a lot more complicated. If you try, you will most likely generate 'out of sync' errors and possibly crash the game.

And by the way, you do not need the game hacking program once you know the addresses. Using a program like Trainer Maker Kit, you can create a trainer and distribute this trainer to all your friends. They can use this trainer to easily hack the game without having to search for those addresses.
