No, you cannot. Because you have to put the codes into the GameShark itself and then put your game in.

You can search for GameShark codes on google by typing "GameShark Codes" and after type for either Ds, Vba, etc. You can also check in youtube and search it but give the specific name and software of the game. Example: 'Pokemon Leafgreen Gameshark Codes'.

no you must have a gameshark to use gameshark code because there is no other way to enter them into the console but if you get a gameshark then many codes come downloaded on them so you don't have to type them in GET GAMESHARK THEY ARE AWSOME
Buy ActionReplay or GameShark, there's a ton of good codes.
You can just manually type them in depending on the system you use, some gamesharks allow you to hook them to your computer and update them or in the case of a playstation 2 one, you can add the codes to a usb thumbdrive and update the codes onto the gameshark memory card for use.
