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:

• Making the player character stronger, such as with infinite lives, invulnerability, permanent power-ups, no collision detection, walk through walls, one-hit kills, super-high jumps, infinite money, etc.
• Warping directly to specific levels.
• The ability to download, upload, import and export saved games from and to the Internet or a storage device.
• Allowing the player to save the game state to disk, so that the game can be restarted from that point even if it does not support saving.
• Region-free operation.
• Loading of third-party or homebrew applications/games.
• Display of internal game data which are not normally seen by the player.

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.
