Hey, beating Emerald weapon is easy. You don't need KotR to beat him, i never bothered getting a gold chocobo (that means i had to go Wsummon-BahamutZero-Quadramagic on Ruby weapon... god, it took me ages! :rolleyes2 i had to look at that Bahamut summonig a million times). Just Omnislach, 4-cut or wathever and use some megaelexirs if needed and he will go down in no time.
