you may or may not know about the hidden feature in Golden Sun 1... By using a button combo, you can access another menu option called "Transfer" or somthing similar. This gives you a few options, all of which are designed to transfer your GS1 data to GS2. The best is using a link cable between two GBAs, with each cart in. Or alternatively, you can enter a code like you would a name. Trouble is, for the best results, the code is many pages long, so you can opt for a short version that won't transfer items and such over... I'll see If I can find a relevent FAQ somewhere...

Edit: (Quoted from a Walkthrough that will clearly contain spoilers!: https://db.gamefaqs.com/portable/gbad...en_sun_2_d.txt )

If you don't know how to get the data (link or password) here's
how:
1. Go into Golden Sun 1.
2. At the main menu, hold Left, R, and press B. You should still
be holding R and Left. The menu disappears for a sec, then when
it comes back, the 'Send' option will be there. Select it.
3. Now choose clear data to send data from.
4. Choose either Password or Cable. If you're doing the latter, it
will connect and transfer the data. If you're using Password:
5. Choose either Gold, Silver, or Bronze password.
Gold has everything: Level, Djinn, Char. Stats, Items, and Coins.
Silver has a bit less: Level, Djinn, and Char. Stats.
Bronze only has Level and Djinn.
Be forewarned, the Gold Password is 260 characters long...
6. Write down the password and enter it into Golden Sun 2.
