Like I said you could be playing it under Linux right now, requirels no Linux skills what so ever!
Just install Debain as is, then download the Scummvm.deb package to your root directory or wherever, and type:
dpkg - i scummvm.deb
I believe those are the commands I used, it will give you some errors during install, but if you right click on your desktop, it will be under the Games menu, or maybe after you refresh X it will.
Either way it was simple, and I suck at Linux for the most part. Another great thing about playing under Linux is you have instant Keyboard and Mouse support!
So how does Zak Run under it, what is new to the FM Towns version that was not in the Amiga version?
