Modification of runtime game data
Cheating can easily be achieved by modifying the game's data while it is running. These methods of cheating are often less reliable than cheat codes included in a game by its creators. This is due to the fact that certain programming styles or quirks of internal game logic, different release versions of a game, or even using the same game at different times or on different hardware, may result in different memory usage and hence the trainer program might have no effect, or stop the game from running altogether.[13] Modifying game data usually constitutes a violation of a software license agreement that prohibits modifying the program at all.http://jedziemyzbitcoin.blogspot.com
Memory editing software
The most basic way of achieving this is by means of memory editor software, which allows the player to directly edit the numeric values in a certain memory address. This kind of software usually includes a feature that allows the player to perform memory searches to aid the user to locate the memory areas where known values (such as the amount of lives, score or health level) are located. Provided a memory address, a memory editor may also be able to "freeze" it, preventing the game from altering the information stored at that memory address.Game trainers are a special type of memory editor, in which the program comes with predefined functions to modify the run time memory of a specific computer game.[14] When distributed, trainers often have a single + and a number appended to their title, representing the number of modifications the trainer has available.[14]
In the 1980s and 1990s, trainers were generally integrated straight into the actual game by cracking groups. When the game was first started, the trainer would typically show a splash screen of its own, sometimes allowing modifications of options related to the trainer, and then proceed to the actual game. In the cracker group release lists and intros, trained games were marked with one or more plus signs after them, one for each option in the trainer, for example: "the Mega Krew presents: Ms. Astro Chicken++".
Many emulators have built-in functionality that allows players to modify data as the game is running, sometimes even emulating cheating hardware such as Game Genie. Some emulators take this method a step further and allow the player to export and import data edits. Edit templates of many games for a console are collected and redistributed as cheat packs.
Emulators also frequently offer the additional advantage of being able to save the state of the entire emulated machine at any point, effectively allowing saving at any point in a game even when save functionality is not provided by the game itself. Cheating hardware such as "Instant Replay" also allows such behavior for some consoles.

Saved game editors
Editing a saved game offers an indirect way to modify game data. By modifying a file in persistent storage, it is possible to effectively modify the run time game data that will be restored when the game attempts to load the save game.Hex editors were the most basic means of editing saved game files (e.g. to give the player a large sum of money in strategy games such as Dune II). However, as happened with game editors, dedicated game-editing utilities soon became available, including functions to effortlessly edit saved data for specific games, rendering hex editing largely obsolete for this purpose.
If a saved game is stored in multiple files, it may also be possible to cheat simply by mixing and matching these files. For example, if one file represents the items in a treasure chest, while another represents the player's inventory, then the player can save the game before and after picking up an item from the chest, and continue play using the treasure chest file before the item was picked up, and the inventory file from afterward.
