[...] Castle Haunt quests [...]
Here is an updated Castlehaunt
and an updated Castlehaunt II
, with the sfx.dat files embedded in the quest, saved in 2.53.
No other changes were made.
I used grabber to export the wav files, and I imported them into the quest, in place of the default sounds in the 2.5x quest format.
If Freedom is still around, he might want to update the database entry with this. Of course, I do not know if there are any 2.5x issues that may surface, playing these versions.
These will run in 2.53.0, 2.50.2, 2.50.1, and 2.50.0, with more possible bugs in descending order (older builds of ZC).
I'm not particularly interested in fixing all of the old quests with custom sfx.dat files, but if you have one or two specific quests that you want to play in 2.5x, other than Castlehaunt, and have trouble using Grabber, I may be willing to update a them for you.
