I remember of an Acorn Archimedes in the lab where I was working in my Ph.D. thesis. It was responsible for controling and data acquisition from stopped-flow kinetics photometer (er... perhaps only chemists'd understand this

). I remember few things about its OS, such the existence of a graphical user interface, and a nice game called Virus (made by David Braben, who programed classical games like Elite and Frontier).
I did't understand what you said, is it possible to run Archimedes programs in Snes/Megadrive emulators?
