    Hi Lucasxrf,

    You're more than welcome to get than involved!
    Can share with you the edited client, server code so far etc..

    There's no complex programming at this stage, just lots of trial&error and debugging necessary to work out the packet structure.
    Current stage is: we have reached world login thanks to AcarX, and have some of the character profile information worked out. We need to figure out the character items and state information so that the actual character can be loaded:


    There is a list of opcodes at https://docs.google.com/spreadsheets...KqQ/edit#gid=0

    Hi, I'm not a computer person, but I really enjoyed this game when it was out. Is there any eta or a website I can visit to be able to play the game or test it.

    Hello, Cipherdec. There isn't any website yet. We are progressing with the reversing the client packets. You can join up our discord if you want to track our updates: https://discord.gg/sEDnpB

    I am interested in this code, mainly what are "l" and "r" for? What are their initial values?
    Also I am assuming that "fiz" is just a macro for a for loop
