To get started, you must first obtain a copy of the specific Everquest client that is compatible with our server. This client is called the Titanium client, and can be found in various places like amazon, or ebay. The reason it must be the Titanium client is due to the way the client communicates with the server. Every time Everquest has a patch, those communication protocols are changed in that version of the client, and will no longer work with previous versions of server communication protocols. For this reason, only a Clean Install of Everquest Titanium will work. There is another client that works on our server (The Secrets of Faydwer client), but this client is unsupported, and you may experience problems with some of the features. It is strongly recommended that Titanium be used, and for the rest of this guide we will assume that it is.
..except it explicitly states in the p1999 getting started guide that this server runs on titanium, and that you only need follow steps 1-5 from the eqemulator guide to connect to the server. I recommend you try that.
