Hi, now I found the answer to uncompress the avi.file:
You can get it to work with a little tweaking: I loaded townmsk1.avi in the
\townavi\ directory into VirtualDub and saved it with 'Save as old-format AVI'.
The result was a 32MB large file, which
I renamed to townmsk1.avi and started W&W. I was able to enter the Town Hall and
leave the city via the eastern gate.
