Instructions
Insert "Golden Sun" into the GBA and turn on the system. At the title screen, hold down "Left" on the directional pad and the "R" button. Press "Start" while holding both buttons down. At the Link screen, select "Send" and press "A." Select "Password," then copy down the password, which is case-sensitive.
Repeat the process with "Golden Sun: Lost Age." The send screen process is exactly the same, except the "Password" screen only has an option to input a password. Copy the password you've written down and press "Start" to accept.
Start the game in "Golden Sun: Lost Age" and check your inventory for the Orb of Force. If you don't have a completed "Golden Sun" game, input the following code for a save with all items:
