The link to AR redirects to the official site, which only offers a queen.1 file.

Apparently the file is used by ScummVM, which is thus required to run the game. But the review page here on Abandonia claims that it can ve run on DOSBox!
Is there any way I can get the original, unmodified floppy files?

I don't want to install more than one emulator for DOS games, and dislike ScummVM (for example, it uses its own annoying GUI instead of the games' own).
