Microsoft Flight Simulator for the Tandy 2000 -- as far as I know, the only graphical game ever released for that system -- contained a single file FS.COM, size 60 bytes. Presumably the Flight Simulator program itself and all its data lived outside the file system and FS.COM simply bootstrapped the real program living elsewhere. There is a byte-for-byte copy of the Flight Simulator for Tandy 1000, 1200HD, and 2000 disk floating around out there and it actually boots -- but says "Disk Error" when you try to actually start the simulator after the initial menu. So I guess someone will need to take a Kryoflux image in order to truly preserve the software... or write a trainer for it.
