Music

In many games, there is a sound test feature either in an options screen or hidden in the game waiting to be unlocked, and it allows you to listen to any of the game's musical selections at will. While Golden Sun has no such feature, Golden Sun: The Lost Age has it hidden as an easter egg within the Battle mode's lobby. It features every single piece of music found in both games, including those normally heard in Golden Sun only, gathered in one place in the The Lost Age game cart for your reference.

To access the sound test, go into Battle mode from the file select screen with the save file of your choice. Then go to the woman in the lower-left-most corner of the area. Normally, she says, "I like my men macho. You...don't work out much, do you?" However, if you talk to her while holding the R shoulder button of your current game system, she will say, "You have a song request?" and a tiny menu consisting of a number will appear. You can scroll left and right to scan from numbers 0 to 96, and when on a certain number, pressing A will play music assigned to that number. You can now listen to all of both games' tunes.

However, depending on the status of your save file, you can only access music which you have heard previously in that file. And even when you save right before the final boss, there will still be dozens of numbers that are inaccessible; these numbers are the tunes from the original Golden Sun not heard in The Lost Age during normal gameplay. When you save a Completed Data File and use that to load Battle mode, all 97 tracks will be unlocked for you to listen to.
