Answer 1

The GameShark is a tool for modifying the play of video games, by unlocking various game modes and objects, using codes, usually for the purpose of cheating.

The GameShark works by changing binary codes stored at specific locations in a game's memory. Because of this, new GameShark codes can be created to affect essentially any part of a game.

A GameShark code consists of a memory "bank", a memory address, and a value to put in that address, in hexadecimal. Most GameSharks have the ability to find the location in memory of any value so that one may discover new codes. For example, if you are playing a first-person shooter and have 10 rounds of ammunition and want to change this to 255 rounds, you would normally activate your GameShark's menu system, and tell it to search the game's area of memory (RAM) for the number 10, which is "A" in hexadecimal. Usually this will turn up more than one memory location, so you'll need to change the value being searched for, for example by using up some ammunition, and then use your GameShark once again to search the group of locations found last time for the new value. Eventually, you will have it narrowed down to one location (some codes may involve many more locations) and the GameShark will report the code for that location. In this case, assume it is "01FFA202". In our example, "A202" is the memory location, "FF" is the value stored therein, and "01" is the memory bank. Memory locations are split up into large chunks of the same size called memory banks. The most occurring memory bank is the very first, "01". Now we want to set our ammo to 255 (the maximum value that can be stored in this size memory location), so we change "02" to the hexadecimal version of 255, which is "FF".

Action Replay is the brand name of a series of devices created by Datel, primarily used for changing the behavior of video games. Currently, Action Replay is available for the GameCube, Game Boy Advance, PlayStation 2, Xbox, Nintendo DS, and PlayStation Portable (PSP).

General:

With the Action Replay, users can obtain objects that are not obtainable during normal gameplay. Example: using the Action Replay to get the "Forbidden Four" NES games in Animal Crossing.
Action Replay allows users to have infinite amounts of limited resources, such as lives, time, money, or ammunition.
Action Replay lets users access levels that are not normally available (most of these levels were usually used for beta testing, or were removed from normal gameplay).
Action Replay can activate programmer menus usually named "Debug Menus" that can be accessed with the correct parameter enabled that are normally unavailable to the player. Some functions/features that are usually included can be of great benefit to the player, such as access to Level Warps, Invincibilty, various Test modes and unlocking various game features in an instant.
