Does any one have any idea how to use the gameshark codes???
Do all the G.S codes work??
I tried for getting master balls & so on..
But failed... :unsure:

*sigh*...wrong forum, as usual.

it depends on what emulator you are using. are you using VisualBoy Advance? if you are, then:

go to 'Cheats' up at the top.
click on 'Cheat List'.
click on 'GameShark'.
type in a description of the code (ex. Shiny Pokemon) in the Description box
type the corresponding code in the Code box
repeat until all desired codes are put in
to activate codes, click the little box in front of the codes in the list so that they have a green checkmark in them.
to save the cheat list, during game play go back to 'Cheats', and go to 'Save cheat list'. enter a file name and a place to save it in. to upload a cheat list, go to 'Load cheat list', browse for the list and click enter.

if you are doing all of this and the codes dont work, make sure you are putting them in correctly. double check after you type them in, its easy to make a mistake. also make sure the code you are putting in isnt a fake, and that it works for the version of the game you have (for example, if you are playing an American Ruby game, make sure you get only a code that is American and works for Ruby.) also, make sure to put in any Master Codes necessary.
