dosemu would be a good idea (theoretically). In fact i have used dosemu
long before i started trying wine. and duke runs fine, that is right.
the problem is just that the fact that a program is a "windows program"
(=uses the win32-api) does not mean that it is not a DOS program (=uses
DOS interrupts and i386 real mode calls) either. There are quite some "DOS"
progs that just wont run in DOSemu or a real DOS because they require
windows and a software real mode server.
And what do i do with those, or first of all - what would you call those?
