no gameshark code is legit
yes; but one at a time
It is entered by having the gameshark & the emerald inserted into the gameshark, then turn on the Gameboy Advance & the Gameshark should have the cheats for that game on the menu, if not they can be entered manually, for the cheats go to their website (they will have them).
