The Send function in the Golden Sun games is a way to transfer game data from the first game to the second game, using either a Password or Game Link Cable. The Password is obtained from the first game's Send menu, which is made accessible by holding left on the D-pad and the R shoulder button simultaneously while pressing Start on the game's main menu. A Golden Sun save file must be registered as Clear Data on the game's Continue menu in order for the Send option to appear, and a The Lost Age save file must be pre-Reunion to be able to receive transferred data.
The Send menu provides two transfer methods:
- Password - allows viewing of a chosen Clear Data file's data in password form.
- Cable - allows direct data transfer from a chosen Clear Data file to The Lost Age via Game Link Cable.
There are three grades of passwords: Bronze, Silver, and Gold.
The Bronze password transfers the characters' names, levels, Djinn collection, utility Psynergy items such as the Orb of Force, and the status of certain Golden Sun story events so as to add and influence story events in The Lost Age, such as Feizhi giving Felix the Golden Ring if Isaac rescued Hsu in the previous game. It's possible to access every dungeon and cutscene in The Lost Age with just the Bronze password.
The Silver password transfers all of the above, plus the exact stats of the original characters, so that stat boosts from items like the Power Bread are not lost. This is useful if the player would like to get a head start on maxing out all stats/levels for Isaac's party, particularly if the transferred stats have been amassed through level-grinding in the first game.
The Gold password transfers all of the above plus the total amount of coins Isaac's party has amassed at the end of Golden Sun and every item in the four characters' inventories. The Gold password is obscenely long, weighing in at 260 characters. Because most equipment from Golden Sun will be quickly outclassed by equipment found later in The Lost Age, it's relatively futile to spend dozens of minutes copying down and inputting the Gold password while attempt to avoid any errors. However, valuable Golden Sun-exclusive artifacts such as the Cleric's Ring, Lure Cap, Elven Shirt, and Storm Gear for example may attract dedicated players to the Gold password.
- The capital "I" ("eye"), the small "l" ("el"), and the number "1" are NOT used. If you're trying to find one of those three characters, you copied something down wrong.
The Game Link Cable transfers all of the above, plus Pause menu settings. In addition, while the Gold password transfers equipment unequipped and Djinn shuffled, the Game Link Cable transfers equipment and Djinn organized among the characters exactly as they were at the end of Golden Sun. However, an advantage to the Gold password is that it unequips cursed items for free.
It's just barely possible to transfer all Golden Sun-exclusive items that the player is allowed to retain to the end of that game to The Lost Age, though there's no additional reward for doing so.
