I just beat Emerald Weapon earlier today! and WITHOUT KOTR, PHOENIX, OR FINAL ATTACK! I just had Cloud, Tifa, Cid, each with 6 or 7 Materia (to keep from dying when Emerald uses Air Tam Storm....which it didn't use). I kept Cid at full MP to power up his Venus Gospel, had him use 4x-Cut, and Cloud Mime it. I kept Tifa with W-Item to power up Cloud and Cid with Hero Drinks, and Megaelixirs to keep from dying.

and, some strategy guides say that Gravity wont work on Emerald. They're wrong. Demi, Demi2, and Demi3 will either Miss, or do 9999 damage.
