I have a question about cheating devices. I am thinking of getting one for my game boy SP. What do you recommend? Gameshark or Action Replay? I have heard they crash sometimes. Is that true? How much do they cost? Buy at gaming store or walmart? Are they worth the money? I want the cheating device for Pokemon games. Legendary Pokemon is what I want it for. Ho-oh, Lugia, Celebi, Jirachi, Deoxys and more. Is it worth it? Can it screw up your game? Please answer my questions!!!!
