Game Shark & Pro Action Replay Information

Game Shark and Pro Action Replay Cartridges

The Game Shark and Pro Action Replay are devices that allow custom cheat codes to be enabled in various console games. Originally developed by Datel Design and Development, Ltd. in the U.K., this technology is known as the Pro Action Replay in Europe, while distributed by InterAct Accessories as the Game Shark in North America.

System Availability

Game Shark and Pro Action Replay cartridges are available for the Sony PlayStation, Nintendo 64, and Sega Saturn video game systems. Each system requires their own version of the device. The Nintendo 64 and Sega Saturn versions plug into the cartridge port on the top of the console. The Sony PlayStation version plugs into the high-speed parallel port on the back of the console.


For the most part, Game Shark codes can be used in a Pro Action Replay and vice versa. However, this assumes that the same regional version of the game is being used on both systems. Since games are often modified when released in various world markets, most Pro Action Replay codes correspond to European releases, while Game Shark codes correspond to North American or Japanese releases. Thus, Pro Action Replay codes for an European version of a game can be used in any Game Shark or Pro Action Replay cartridge if that version of the game is being played in that machine. However, those same codes in that same machine will not work if the U.S. version of a game is in the console.


If you're familiar with the Game Genie or Action Replay cartridges used in the 8-bit or 16-bit video game systems, then you already understand the concept of the Game Shark and Pro Action Replay. As a game runs on a video game system, specific locations in the consoles RAM memory are used to hold important information, such as the number of lives remaining, shields, ammunition, current game level, etc. The Game Shark and Pro Action Replay device is able to override the values in those memory locations, allowing the game to be played with unlimited lives, always full shields, unlimited ammunition, etc.

This capability is a distinct advantage, especially in games that don't have built-in cheat codes. A large number of games can now be mastered by using internal codes from the cartridge, or by entering custom codes found in magazines, 1-900 tip lines, or web sites such as this.

Joker Commands

Joker Commands are special Game Shark/Pro Action Replay codes. Simply stated, a Joker Command allows a Game Shark code to be momentarily activated when a button or combination of buttons is pressed on the controller. This differs from standard Game Shark codes, which are always active during game play. Joker Commands are very useful in situations where a Game Shark code will lock up the system while the game is loading or in other areas.

Theoretically, every game can use the Joker command feature. Any Game Shark code can be with a Joker Command. A Joker Command can be entered as a Master Code, which will turn on all codes that are enabled when the Joker button combination is pressed. It may also be used with an individual code in the regular code box, by entering the Joker Command as line one, with the remaining part(s) of the code listed underneath.

Rear Port

The PlayStation and Saturn versions of the Game Shark/Pro Action Replay have a male connector on the rear of the cartridge. It's used by InterAct or Datel to upgrade, or "flash" the software inside the cartridge. It's also used to connect the cartridge to a PC to allow new codes to be hacked. A Comms Link package is required to provide the PC connection.
