How do you transfer clear data from golden sun to golden sun - 2?

There are two possible methods to do so, once you have beaten Golden Sun, at the black logo screen hold L + R + Left and press B. This will activate an option called transfer. Select this option to either transfer data through a link cable (Requires two Game Boys) or receive a passWord in the form of letters and numbers which you can enter into your Golden Sun 2 game to transfer the data. If you use the passWord option you can choose from one of 3 levels of passWord. Higher levels are longer and harder to enter, but allow more data to be transfered. (The link cable option transfers the same amount of data as the highest passWord)
