Meh .. I'm being stupid ...
I mean the .dll files TDWFileUtils.dll and TDWUtils.dll .. but I doubt they are changed now .. and I should be paying more attention :p
I am using the JSGME method to put the generic patcher stuff into my game .. as per
instructions found here, adapted a little for missing files the new patchers looks for.
I went on the assumption that needing them means changing them .. which seems to be in error :p
