Hello,

After installing the game and dosbox, with the option to add shortcuts, I launch Battle Isle 2 using the corresponding GOG shortcut.
First, there is no menu (maybe it's normal). Then after the introduction videos and finally entering the game, I have a crash to desktop "DosBOX had a problem blahblah".
I have Windows XP.

You know that you don't need Dosbox for this Version? The Gog-Versions usually work on their own whithout using Dosbox.
Have you tried to start the game with the shortcut normally?

Technically they use DOSBox too. You just don't have to manually run it beforehand.

Yeah, that is possibly true. But I don't know if you have to install it for you own or if it is included in the GOG-Version. I don't have bought this Package, because I owned the Game already (and use it with Dosbox from time after time).
But the other game I've bought from GOG is running fine. I had installed DOSBox already, surely an older Version. But I am not sure that is a necessarity.

What I wanted to make sure is that you didn't try to start it IN DOSBox directly. Because that would be surely a problem.
