Morrighan acts as a kind of proxy, it makes the client connect to a special local server that forwards all packets from the client to the actual server. This way it's able to read every single packet that gets sent or received. These packets can then be passed to other applications, so they can work with them, e.g. loggers like MabiPale2.

##How to log packets

Let's assume you want to log packets from NA. Instead of launching the client through the patcher, you would create a link/bat, like you would to connect to a local server, but with the NA IPs. And instead of client.exe you would use Morrighan.exe (which you have to put into your Mabi folder), that's it.

Morrighan.exe code:1622 ver:143 logip:208.85.109.35 logport:11000 chatip:208.85.109.37 chatport:8002 setting:"file://data/features.xml=Regular, USA"

What will happen here is that Morrighan reads the parameters, replaces the logip and port with the ones to a new, invisible local server it started, and finally starts the client. You will see a little window in the upper left, to let you know that Morrighan is running. Once you see that window, you can use a tool like Pale to connect to it and log packets.

The window closes automatically when the client gets closed. You can also double click it to quickly close Morrighan and the client.

##How to connect to Morrighan

Morrighan uses the same API as the tool it was inspired by, "Alissa". It uses WM_COPY messages to communicate between Morrighan's and the subscriber's window. To subscribe to Morrighan, to receive packets, you send the "op" (dwData) 100 to Morrighan's window (window name: "mod_Alissa"), to unsubscribe, you send 101. While you're subscribed, you receive all incoming (op 0x10101012) and outgoing (op 0x10101011) packets via the same method.

For an actual example on how this works, I suggest looking at the corrosponding functions in Pale. Alternatively you can also create a plug-in for Pale, which will be easier.

##Restrictions

Morrighan only supports the Login and Channel servers, you won't get any messenger packets, it lets the client connect directly there.
