I have to agree some of the stuff that is being said here.
If you actually want to contribute to this project, do not bug the developers, at least not until you have exhausted all the options yourself. If you want to reverse engineer the client. There is plenty of tools information about it on the web. If you want to play around with the source, it is on the GIT, you can get the basic emu going. If you want to write your own emu, there are plenty of other emulators out there where you can look at the code and figure out how to write mob handlers, auth server, magin server, quests, and everything else.
The information is out there on the internet, if you take time to find it. From my observation, most people get lazy and rather than trying to learn, so instead they make big posts how they want to help, without actually doing any of the ground work. Do your research before asking questions and everyone will be happy.
Someone once said to me, learn how to "ask the right questions". Don't ask "How to make emu?", do some research, experiment with writing emulator yourself and when you have exhausted all the options, ask questions like "i have updated the emu code to handle mission rpc, but sometimes the client does not respond, any ideas?".
Do not try and play The Matrix Online as you used to. That's impossible. Instead... only try to realize the truth. There is no Matrix Online. Then you'll see, that it is not the The Matrix Online that is getting played, it is only yourself.
