I am not sure how much time I'll actually have on my hands since I am a full-time JEE/full-stack developer (at work), but I got my hands on the 661 server source. If there is a newer source available (along with a client), please let me know so we can save ourselves some trouble.
Currently I'll be trying to get the realmserver to work good enough so it lets one join the game (when started along with the database and gameserver).
Since I already have a job, my time might be a bit short and I also do not know if I will manage to fix it so it at least works somehow, but I'll give it a try.
I am not interested in paid offers nor in sources, that are not supposed to be made publicly available. If I achieve anything, I'll be releasing it to the public here on RageZone. So if you are not okay helping me because of this - it's okay. But if you do help me, please keep this in mind.
