The Lunar Ruins possibly wasn't ported to the DS remake, hence the title, "GBA- Exclusive."
After finishing Final Fantasy IV Advance, there are a number of things you can do. You can explore the Lunar Ruins. There are 10 different trials in the Lunar Ruins, each resulting in a weapon or item or great importance. You can also travel the worlds and fill up your bestiary, if you haven't already.

The DS version was more focused around developing your five main characters fully by using the augments, and by having a new game +, and then a new game ++. The lunar ruins on the other hand was part of the GBA version, which allowed you to use most of the temporary characters again, and had ways of developing them. The two systems didn't really mesh. Having the main characters get the augments didn't really mix with one where the old characters could still be used. Taking your main team through the game three times didn't really mix with having to deal with 10 characters and a huge dungeon where virtually none of the items you got could be carried into the new game +. So they went with the exclusive Augment system and dropped the GBA Advance version's specific areas.
