How to Create Gameshark Codes

GameShark is a brand of cheat devices available across several gaming platforms, where players can modify their games by entering 12-digit cheat codes into the cartridges. This process creates effects within the game that were not originally programmed. Although most games have hundreds, if not thousands, of pre-made codes, players can create their own codes if they desire. Developing codes requires a basic knowledge of binary and hexadecimal coding, but can be useful when customizing game content.

Instructions

- 1
  Use a 810 or 880 to start the code if you wish to create an effect. Use D00 to modify design aspects of the game.
- 2
  Determine the next three digits for how the code will work in the game. These digits will also be responsible for what aspect of the game the code will appear.
- 3
  Choose two digits that will determine what the codes is used for. Use 3C for altering player health and F5 for altering enemy health. Use FF for ammo, F3 for weapons. and 75 for maps.
- 4
  End the code with the final four digits. These digits don't have any specific purpose to them, other than to complete the code. Use 0000, 0001, 0030, 0007, 3F80, 3C80, or a sequence of your own.
- 5
  Load the code into your GameShark the next time you start your console.
