Hi,
Any reason why you wouldn't play the CD32 "talkie" version of Battle Chess in the meantime ?
(I have a good reason to ask, as often, it will become clear once kitty has replied)
By the way, if you don't mind sacrificing a little visual fluff, and are in need of a more serious challenge,
Colossus Chess X is the game you need
(and its preinstalled doesn't require registration).
