If you want to add gameshrk codes, put the game in the gameshrk and turn it on. Go to select gamecodes and add Harvest Moon 64. Then click add new codes and type in whatever code you want and click on it. Afterwards, click cancel until it shows the option, start game. Then click it and start the game. Just don't take out the gameshark! If you were not talking about the gameshark, sorry. Thats the only way to put in codes.
