Isle of Dread: An Approximation

I spent a few hours putting together the following approximation of the classic X1: The Isle of Dread setting in Hexographer. I wonder if anyone has a better version? In Hexographer format that is? If not I'll try to fix the remaining bugs and I'll post the actual Hexographer file sometime tomorrow for others to reuse. But it's hard to believe that nobody else has done a version of this classic before...
