Guys, lemme put this to rest. Since this is a spoilers topic, no one is going to be hurt by this. The zones are the following:
Jade Coast Zone -> Mudhole Karst Zone (Green emerald, #1)
Tempest Valley Zone -> Rainstorm Keep Zone (Orange emerald, #2)
Verdant Forest Zone -> Labyrinth Woods Zone (Pink emerald, #3)
Flame Rift Zone -> Vulcan Forge Zone (Blue emerald, #4)
Midnight Freeze Zone -> Frost Cavern Zone (Red emerald, #5)
Sunken Plant Zone -> Nitric Citadel Zone (Light blue emerald, #6)
Aerial Garden Zone -> Starlight Palace Zone (White emerald, #7)
The black emerald, #8, is nowhere in Mystic Realm 4. You can't find it unless you alter the file. Now stop using the MAP command and play the game yourself. You might find that I'm right if you stop cheating ^_~
