Seems the developers are fairly active on the Steam forums, I'll go ask, even though I don't have an OS4 machine. I'm guessing since it uses OpenGL it shouldn't be too terribly difficult, but then again I have no clue.

P.S. Only the first one ever came out for anything besides DOS/Windows. But as far as I know, they're remaking all three.
I really really hope they do not remake the other two, when this one went on sale it was not even a working game, 7 odd months down the road and they are still patching, it is still very far from polished and still contains many bugs and glitches, and some people are still getting show stopping bugs. There are games sites selling it really really cheap as in $5 including the DLC, suppose its a bit of fun at that price. DLC that is another bone of contention, they release DLC while still patching the game and the DLC brought in more bugs. Also the game runs to a time limit so does not adding all the extra DLC stuff mess that up, they say no, I say yes, because when I played it on the Amiga years ago I actually encountered that time limit, the orcs invaded and GAME OVER.
When you look at the options screen etc in game they really look like bedroom amature stuff

As I say I really really hope they leave the other two alone and leave these historical RPGS as they are.
