There is currently some lists, although not comprehensive, of original game
bugs in the ScummVM wiki. If you go to
There are lists on both the 'Tinsel TODO' and 'Tinsel Bugs' pages.

Someone with time available could usefully make a list of all such problems.
Some of them can be fixed. Others, such as when a different voice says a
given line, can't be fixed.

 Many of these are due to bugs in the scripts for the GRA version. For
example, I remember one bug when talking to the Arch-chancelor, the voice
sample played doesn't match the subtitles exactly (i.e. some of the voice
sample for the first line was included in the second line). The SCN version
cleaned up most of these problems, but introduced a few new ones. Such as
when you talk to the Lecturer in Recent Runes, and the subtitle says "No no
no", the voice sample instead has Rincewind saying "Did you get the number
of that donkey cart".

I can't remember anyone mentioning that one specifically.

This is a known one. It's uncertain whether it could be fixed, since it
would involve mucking around with the scripts and/or raw animation frames
used in the cutscene.

I've noticed that too. From memory, it happens in the Lost Temple of Offler,
for example. As with the 'No no no' one I mentioned above, it can't really
be fixed, since the voice sample is being played correctly.. it's just the
original developers used some other actor other than Eric Idle for some

Looking at the Wiki, we currently have 'Perfect Entertainment' listed as the
publisher. Psygnosis were the developers, not the publishers, correct?

Adding bug reports is likely a good idea, so long as you look through the
previous ones to ensure you don't add duplicates of already existing bugs.
It means that the bugs will all be properly identified, and where they are
fixable, we can fix and then close the bugs, leaving a list of bugs that
can't be fixed, but are at least identified as being problems in the
original game. The Tinsel engine already has workarounds for ten different
script bugs, and most of these are for bugs in the Discworld 1 GRA version,
so some bugs you identify may be fixable.
