Overall, Aces of The Deep is another classy Aces sim that requires a fair amount of strategic thinking while successfully capturing the feel of the era. Great fun! BTW: You can still find your patrol area without the map. On the global chart, when you plot your course, the IDs are shown at the bottom of the screen. So with a little searching you can find your patrol area. This is the floppy-disk DOS version. There also was an updated Windows version released on CD-ROM in 1995 called Command Aces of the Deep, which you can download from this site :)
Note: This one only works in real DOS mode. The expansion disk can only be installed by using SUBST or by installing it from a floppy-disk. The patch to version 1.2 should be installed after the installation of the expansion disk and not the other way round. The expansion disk - downloadable in "Extras" area below - adds brand new missions, areas, and a special prototype XXI U-boat submarine.
