Hello!
EarthWatch (a sundial) is the ONLY of my 600+ DOS programs that won't run. The (rather simple) program (EVW35.exe) starts in full-screen under Windows XP (no need for Win95 compatibility mode) and shows a colourful sunlit/dark map of the world = it works. But under DOS-Box all i see is black. The prog starts, switches to VGA-graphics mode (after a second DosBox window becomes slightly larger) and then there is black (even at day). It does'nt crash, CPU is almost idle... it just does nothing (i can see) until i quit it regulary (Q or ESC)... There are no error-messages and i'm through with any imaginable DosBox setting (that i know of) ...

Greetings from 52°12'N 8°43'E Jens

The blank screen happens when the app can't find map files. There are some batch files (COPYM1.BAT, COPYM2.BAT, COPYM3.BAT) that copy the map files, but they rename the copied files with wildcards, which DOSBox's internal COPY command does not support.

So, you'll need to type more commands:

1CD \EWATCH
2COPY MAP1.RED TEMPMAP.RED
3COPY MAP1.GRN TEMPMAP.GRN
4COPY MAP1.BLU TEMPMAP.BLU
5COPY MAP1.INT TEMPMAP.INT
6EWV

For convenience you could make new batch files to copy the map files like the above example.
