I start up the gameshark and i put the codes i want on and i make sure the m code is on but when i start my game nothing happens it's just my regular leaf green game.

http://www.atariage.com/forums/topic/132541-some-help-with-my-new-gameshark-pro-3-3-for-n64/ Check this site... Check the pins in the cartridge and the game shark... Try with different games... Make sure its clean and making all connections. :) hope it helps.

all you need is to have the gameshark disc and memory card other wise the disc is useless when u put the disc in make sure u have the memory card in too enter the codes save them to the game shark memory card and then reset the system and then put ur game in and u should have the cheats i hope i helped me and my two bros had the same problem

keep (m) on and other codes on. Sometimes when you use codes to get all the items in this game too early bad stuff happens.

Same thing with me email me at [email protected] if you solve your problem, I'd really like to know -_-'

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 It is possible that you can find a newer version of the GameShark that would work with this so called "blocked" games, but it might be difficult.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

Your Gameshark mightve been used too much so now it glitches and stops.

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

It's because the cheats are designed for the GBA not the DS.

Though you have the right game, it just wont work.

there is no codes for pokemon emerald
