About the revision historyThis is a
comprehensive list of the features added to Zentris for DOS in each
version from 1.20 to 1.62 (which was the final version, released in 1992). The
feature-set is cumulative, except where noted, so features found in any earlier
version will also be found in all later versions. New features in version
1.62 - June 10, 1992- Added dates to the high score list, and a
menu option to select either American or European date
formats.

pull-down menus to the introduction screen.
New features in version
1.60 - May 23, 1992- Save and Restore Games
- Multiple piece styles
supported
- Rewrote joystick routines

This

viruses. It uses multiple 32-bit CRCs, and is quite
fast.
