I got a copy of "Das schwarze Auge - Nordlandtriologie" from Jowood and inspected the installation medium to get a working installation under my free operating system of choice. It has only one interesting file - Setup1.cab which can be extracted by cabextract. Of course, this will result in a non working directory structure but this is nothing we cannot fix. (I will skip the InstallShield script stuff here)

#! /bin/sh
set -e

cabextract -L Setup1.cab

Anybody noticed the dosbox stuff? - Yes, it is just starting dosbox 0.72 under windows and we can do the same under linux (and many other platforms). So let's take a look at the details. Every folder has an own dosbox.conf which helps a lot with the non trivial setup. We only have to start dosbox with some extra parameters in our dsaX folder to get the real game started.

dsa1

dosbox -conf dosbox.conf -c 'mount c .' -c 'c:' -c schick.bat -c exit

dsa2

dosbox -conf dosbox.conf -c 'mount c .' -c 'c:' -c schweif.exe -c exit

dsa3

dosbox -conf dosbox.conf -c 'mount c .' -c 'c:' -c riva.exe -c exit
