Welcome the UO Demo Wiki.
UO Demo or UODemo refers to the Ultima Online Demo released by Origin Systems Inc in 1998. It was, like the name hints, an offline playable demo of the Ultima Online game back then. The information in this wiki is derived from reverse engineering the demo consisting of one executable file and one data file.

UO Demo Files
Files on the UO:The Second Age retail CD
After installing UO Demo you see two files : uodemo.exe and uodemo.dat.
uodemo.exe is the executable, it contains authentic server code and a full client.
uodemo.dat is encrypted using the GOST block cipher [1]. The keys to decrypt the file are inside uodemo.exe but I'm not sure it's legal to post those keys here. See also .rundir.
Modified UODemo Files
UoDemo+. (UO Demo Plus)
The uodemo+.exe is a modified demo executable to help unleash some of the secrets within.
UoDmClnt. (UO Demo Client)
The UoDmClnt.exe is a modified uodemo.exe to act as a real/pure client without calling the server functions.
