Runescape Private Server Coding Help [317]?

Hello i am currently in the process of coding a Runescape Private Server and want to know if anyone could help me. I want to add some Ancient Curses to my Server [Turmoil and Soul Split] and i also want to know how to code Custom Emotes into the game, Such as when wearing a Owner Cape you can press the skillcape button and your character sprouts wings and rises above everyone else and turns into a God holding the world then slowly fall back to earth (or maybe i have to stick with the precoded emotes -.-) anyway i would like to know how i can code those items
