YAZI 1.01 - now updated for Newton 2.1, and taking full advantage of the hardware keyboard and other 2.1 enhancements. YAZI is a "text adventure engine" which takes "datafiles" as input and allows you to play them on the Newton. Strictly speaking, YAZI doesn't do anything on it's own; it requires a games datafile to run. The datafile contains all of the information about specific games.
