I'm not there yet but in the guide (picked it up for $3 on ebay) it says: After defeating the final boss and completing the game, start your saved game and head to El Forado. Talk to the elves to learn about the Yggdrasil flower that has the power to restore life. One elf says, "When you find a place changed, that may well be a sign that the flower has blossomed." While traveling around, you soon notice that The Azimuth has changed. In one location, a hole has opened up on the northern altar. Drop into the hole to enter a very mysterious dungeon. This dungeon leads you down through a wide variety of levels....big dungeon, strong monsters, 30 treasures, Boss fight vs. two heavy hitters, Foo Yung and Chow Mein.
After defeating them, exit the dungeon and fly to El Forado. Climb the tree to very top to find blossomed Yggdrasil flower and examine it. Head to Rosehill and use the flower in front of Rose's grave site. She revives and wants to find Psaro!!! Go to Nadirria and go through the castle. Find Psaro in the same spot. Rose convinces him to join your party!!! He can equp cursed equipment with no side effects.
Zoom to Diabolic Hall, head to the throne room to fight Aamon. After defeating Aamon, Psaro leaves the party and your warped to Zenithia. Talk to everyone there and then leave the castle to complete the game. After credits, save and restart, you're back in Endor and Psaro rejoin.
You can run through special dungeon to fight Foo Yung and Chow Mein again. Each time you win +nets you some of Psaro's special equip. 2nd Pandemonic shield, 3rd, Pandemonic sword, 4th, Pandemonic Armour, 5th, Boxer shorts, 6th, Yggdrasil Leaf, 7th, Old Man Psaro as a citizen for Hoffman's Place if you have castle he's in back room.
Hope that helps
