Modified Crafty 17.14 w/ "booster 120 120 0" settings - "booster" is a new
option addeed to modified Crafty 17.14 that extends the extensions further.
Final testing still underway.  Modified Crafty will be available by email
(mfbyrne_pa@msn.com) and it will be emailed to everyone who requests it upon
completion of final testing.

Although nodified Crafty 17.14  can sparkle on some of these "position tests" -
game play has been disappointing so far - thus the delay in the release.  Sorry.
