So I said 'theoretically' now I will say 'Technically' with no creation kit, Mod manager or level editor for most games you will be doing this by hand.

The only small difference is most games do not come with an editor like Fallout mod manager or Skyrim (CE) Creation kit. WARNING: Do Not Abuse This info, some may say that this is theoretically cheating, but for own personal use it is actually modding as in the same way one would MOD Skyrim.

A simple guide to teach you how to create your own Gameshark / GameGenie with ease.

Here is a screenshot of the cracking video in. Thanks go out to Spiffomatic64 for this video. I would recommend that users download the video pack and the crackme all neatly provided in the link below and try the entire process themselves. This video is a highly recommended watch for budding reverse engineers! Once the code in these routines have been understood, he proceeds to patch the binary to convert the crackme into a keygen. He first verifies using Peid that the program has not been compressed or packed and then loads this program into Ollydbg, disassembles it and then proceeds to find the place in the code responsible for the annoying alert message shown in the beginning and then finally the place responsible for the key validation checks. He then uses a simple crackme prolixe_keygenme1.zip to show how software crackers work their way through a binary.

how to inspect memory / code in a running program.

Spiffomatic64 starts with a basic introduction to the tools of the trade - Ollydbg and Peid. In this awesome video created by Spiffomatic64, we learn about the basics of software cracking. This allows users to generate arbitrary valid keys / serials for the program. Alternately, he can also reverse engineer the key / serial comparison routines and write a keygen for the program. He then proceeds to alter the behavior of the program by finding and changing (patching) the routines responsible for the security mechanisms, in order to allow full unlimited access to the program.

A Cracker works his way through a program by disassembling it and understanding the security protections built into it. Generally software cracks are distributed in the form of patches to the original software or keygen programs which generate arbitrary key / serial combinations. Software Cracking is the art of breaking security protections in a software.
