Despite the fact that computer games are designed to entertain people, they often only cause irritation and resentment. The first reason is the rules (character mortality, a small number of cartridges), the second is too high complexity, forcing you to go through the same moments several times. To combat these problems, users have created trainers.
Suppose that the passage of a game causes you serious difficulties, and even on the "easy" level of difficulty, you die over and over again. The problem can be solved relatively simply: you need to get into the insides of the game and set the number of lives to "infinite", and the number of cartridges to "999".
At the end of the 90s, the games were quite simple technologically, therefore, any user could carry out such a hack, for example, using the ArtMoney program. This software works with the computer's RAM and, with the help of some simple procedures, helps you determine the only memory cell that stores this or that information about your character. After gaining access to the address, the player, of course, is free to do whatever he wants with the value.
However, today the use of ArtMoney is difficult: large projects use a huge amount of RAM, the verification of which is a much more complicated process. Therefore, a number of new programs of this kind were created, with a new common feature: saving the results into a separate exe-file.
Thus, once you "break the game" using, for example, Trainer Creation Kit or Cheat Engine, you save the results in a separate application, "trainer". Now, in order to get immortality, a large amount of money and any other bonuses, you just need to launch the previously created "assistant", which will automatically perform all operations on working with RAM.
On the vastness of the worldwide network, you can find an endless number of trainers for any game. Almost all of them are equally efficient and differ only in a set of bonuses, the number of which is reflected in the file name ("Crysis Trainer + 12"). To use them, the user needs to download this software, place the files in the directory with the product to be cracked, run the trainer, and only then the game itself. Now pressing during the passage of certain keys (set each time individually) will activate cheats and, as a result, bonuses to the player.
