1. An unofficial patch, that fixed some item and quest bugs. One fix was that you could ask about the crash site from Virgil (with voice!). And no, I don´t mean the unofficial patch found on this site (adds the ship cargo etc.)
I think that that was a part of Chris Beddoe's Hard Arcanum, I'm not sure if its part of Car Arcanum.
Ok, I found this. If others have interest, the patch can be downloaded here: http://users.raketnet.nl/renevandepol/ The patch contains a handfull of bug fixes. If I remember correctly, the ending credits let´s you assume, that the player got out of the Void. So one could add a script/charecter that teleports you back to arcanum?
