Reverse-engineering the 1998 Ultima Online demo server

In any MMORPG, the average user will generally only encounter the client side of the system. This makes building a compatible open source version of the proprietary server into a bit of a chore. Of course, sometimes you get a bit of a break, such as with the – still active – MMORPG Ultima Online , when the disc for the 1998 The Second Age expansion contained a stand-alone demo.
