Technical Details Warning
While the encyclopedic nature of the codex means that many articles will have information that could spoil some minor aspects of the game for newer players, this article is known to contain technical information about the game, game engine, data files, logic, etc. This information is not generally useful to the typical game players.
Continue reading at your own discretion.
This page contains decompiled conversation code from Ultima Underworld. The original files came from Paul Carr and are currently archived here.
This file has been modified from that source (by Sir Robin) in the following ways:
local variables holding pointers to string text have had that string text specified in a comment on that same line. This should make the conversation code easier to read.
strings (both dereferenced ones in the code and also the ones added to comments as specified above) have been highlighted for easier reading
function definitions have been anchored and function calls have been linked, to make it easier to follow the flow of the code
