Beat the game once to unlock the Lunar Ruins. Inside there will be a trial for each of your characters but to unlock these you must beat the final boss with each character atleast once.

An eight floor dungeon containing weapons and armor for the party members you couldn't use for the final dungeon in the original. Once you unlock Party Switching and head back to Mysidia, you'll be informed of a new challenge at Mt. Ordeals. A scene will occur once you get there and the Cave of Trials will be accessable.

The Developers' room is now renamed to the 1991 Dev Team Office.
To get there, reach the Underworld for the first time. After gaining access to the armory (after beating Golbez in the crystal room) go down to the Weapon/Armor room and go behind the pillar between the two shop desks. From there, go up, you'll then be in the Lali Ho Pub (another secret room). Then, go right to where there's a dark marking on the floor and progress right through the wall and down a stairway. You will now be at the 1991 Dev Team Office entrance, where you can talk to the developers of the original game, complete with their rank back when they worked on the game in 1991.
