Well, I don't actually know what is wrong with dos4gw.
It is probably something subtle with int21 functions. However,
why it hangs is something I haven't checked out.
You could try running those programs using DOS32A (DOS/32 Advanced)
extender. It seems to work quite well. I just posted a patch that
is required to get its installer working, though, so you might
have some trouble unpacking it...
If you get those games to work under dos32a you will probably find out
that Wine SVGA support is lacking. That is something I have considered
to fix if I can find the time to do it.
