It is possible to extract a working game from the files, there is probably an easier way than I did it. If you use
http://sourceforge.net/projects/innounp/ you can extract the files the ones that are broken in my set are these avoid them and your good.

The one that freezes unpacking is CombatMoveAround the others produce errors. Unfortunatly I'm either too stupid to figure out how or the program doesn't allow simple ignore file so I had to unpack using wildcards which was a bit of a pain. There are guis that use it so I imagine they are the way to go if you wanna give it a shot. (edited to correct files affected and behaviour description)
