#1Put the gameshark in where the game would go, plug the game into the top of it. Turn on your system. The gameshark screen should show up.<skip to #2 if this works> With certain games, such as Majoras Mask, you must first turn it on with only the gameshark plugged in and enter a code first, it should then lead you to a prompt to turn off the system and plug the game into it and turn it back on. Do that, and you'll be right here at #2. After that, follow the stuff on the screen to do whatever to the game you plugged in. It should guide you to an option to boot the game.
Hope this helps. ^^

The original GameShark for the N64 only works on certain games. During the N64 era, game creators would often include code on the game itself that prevented the use of a GameShark. It is possible that you can find a newer version of the GameShark that would work with this so called "blocked" games, but it might be difficult.

I'm assuming that this is the GameShark Pro for the N64. If so, the button is used to find and create your own cheats, such as infinite life, infinite ammo, etc...

To use this feature, start the game, say a first person shooter, and load into a level and when you are ready to begin playing, press the button. The GameShark screen will show up and you can say "search for code" or "search for changes" something like that and the game shark will run a diagnostic that it shows on the screen. A number will appear noting the number of lines of code executed since the game loaded. When it is finished, press the button again and it will return you to the game exactly as you left it. If you are trying to get infinite ammo, simply shoot once and press the gameshark button again to search for codes again. When it is finished, the number it shows will be much smaller, since much less lines of code have executed since the last run. Press the gameshark button again to return to the game and continue the process until you have only a few, say 5 or less, or even just one code left on the gameshark diagnostic. This code will be the one that dictates the amount of ammo that you have. By altering this code with the gameshark, you can either start with an extremely high amount of ammo, or have infinite ammo entirely. The key to this strategy is to do as little as possible between code searches so that you can quickly narrow down on the code that you trying to alter. Hope this helps.

Sounds like the game shark died, sorry for your loss

Gameshark and other cheat codes have a tendency to mess up or freeze the games. This is usual.

Possibility that your gameshark is damaged.
try using a friend's, and if it works you need a new one.
Good luck!
