Hello and welcome, good to see you!
ServUO is arguably the public emulator furthest along in development right now, we had a burst of development right before the holiday season but have slowed down now as everyone is busy with their families or exams. I am sure it will pick back up soon though. I know I will be working on some stuff as soon as xmas is over.
We are mostly accurate up to SA. We still lack High seas content and the new expansion. We worked out the new trading and gold system in the new client though and Voxpire is working on cracking a new file that contains the new multis as well as working on a generic UOP reader. (Basemulticollection.uop)
We try to stay away from customs, only adding quality of life stuff for staff members. We try to stick as close to OSI as possible from the player's perspective, even though we are missing a lot from the last 2 expansions.
