The main thing i want to know is if this game uses the gbalink function.
If you finished Golden Sun 1 and saved it right at the end you get a "complete" save which could then be transferred to Golden Sun 2 (by linking up 2 gba) allowing you to carry over all the djinns gold and items into Golden Sun 2.
I wonder if you have Golden Sun 2 with a complete save in Slot-2 while booting the DS game, if will it unlock or give you something something special. I fucking hope so.
I'm sure those who finished the GBA games are thinking the same thing so let us know if you find out
