Hi there !

I'm writing a header tool/frontend for the Sega Genesis emulator
"GenEm" with DJGPP/Allegro (based on my Magic Engine Header Tool
MeTool). 
To run the Emulator with a given rom I use "spawnvp".
The Emulator is started correctly, but when I exit it, my
program crashes.
Let me note here, that I shut down allegro before spawning, 
and the whole code works fine when I execute a program
written with DJGPP or using the DOS4GW-extender.
GenEm however, uses PMode/W and is additionally compressed
using PMWLite. So it's no option to run Genem with
"Dos4GW Genem.exe" which should normally skip the PMode/w
stub or to stubedit GenEm back to using Dos4GW.
I also tried __djgpp_exception_toggle() (or similair) before
and after the spawn but it didn't help.

So is there anybody out there who can tell me how to spawn
a Watcom protected mode program using Pmode/w (compressed) ??????

Any help welcome !

regards,
vOlker
