Since its esa-protection you surely won't find anybody around here scouting you to a file-download of the vga-version... Maybe you'll have some luck with ebay?!
And another chance - but I'm not sure about it at all - could be a remake of the game...
EDIT: Well, as you can see here

the game's second part is still in progress. So I believe there isn't a remade first part of the game.
Something completely different and off-topic: I had some problems putting a link in my post. For example there isn't the possibility to disguise the link anymore. Will this be fixed in the future?
