Zarch actually started off as one or two level technical demo that came free with the archimedes.. I remember everyone's jaws dropping when we were shown it at school..
There was lost of arguments at the time between the one person in the class who had an archimedes at home (there was always one) and the hoards of Amiga owners (ie me and my mates
) wether the Amiga could handle the graphics but a while later Virus was released on the Amiga and that settled it.
btw.. I too have the complete Tosec of Archimedes on my ftp but I dont recall seeing Zarch in there!?!
