Action Replay

 
Action Replay is the brand name of a cheating device (such as cheat cartridges) created by Datel. The Action Replay is available for many gaming systems including the Nintendo DS, Nintendo DSi, Nintendo 3DS, PlayStation Portable, PlayStation 2, GameCube, Game Boy Advance, and the Xbox.
Typical features.
Typical cheating options include:
Action Replay DS and DSi.
Also known as Action Replay for the Nintendo DS system, this device is a part of the main series created by Datel. The device usually comes with a cartridge, a software disc, and a cable to connect the device to a computer. Unlike future iterations, these versions communicate directly with the game's memory in real time. Because of this, the desired game needs to be inserted within the cartridge and then inserted into the system. Codes are created using the hexadecimal numbering system, and while Datel supplies a rich base of codes, users are given the ability to create their own codes.
Power-Saves.
Power-Saves by Action Replay are a related series of video-game cheat devices. Unlike the main Action Replay series, which cheats by modifying the game code itself, Power-Saves store the game saves created by Datel, allowing users to cheat without modifying the game code being executed. 
Power-Saves are available for game systems such as the Wii on an SD card and the Nintendo 3DS.
Versions for computers.
The ISA-based Action Replay needs memory-resident drivers for both the real and protected mode. The card has a grabber, a trainer, and a slowdown feature. It can also interrupt the current game or save it to disk (freezer).
Models running firmware 4.0 and beyond use EEPROM instead of ROM and thus are upgradeable.
In December 1998, Datel released a version for Windows 95/98.
