Reverse-engineering the 1998 Ultima Online demo server | Hacker News

Researchers and fans discussed reverse-engineering the 1998 Ultima Online demo server.

The thread broadened into UO emulators, private shards, and tools like TazUO, Memento, Razor, SteamUO, and Sphere.

Commenters noted that protocol reverse-engineering still matters for preservation, experimentation, and studying early MMO design.

The discussion also touched on client scripting, network programming, and the long tail of Ultima Online on modern systems like OSX.
