--- Comment #3 from Michael Müller <michael at fds-team.de> ---
The next problem is easily visible in the log. The application tries to setup a
protected mode exception handler (int 0x31 - AX 0x203) for debug exceptions
(0x1), but this is not yet implemented in Wine. Afterwards the application
triggers a single step exception that should be forwarded to the registered
exception handler. Wine ignores this and can't handle the exception itself,
eventually terminating the application.

I don't think it would be terrible difficult to implement this in Wine, but I
fear the chances are low that someone capable of implementing this owns the
game. Writing tests for DOS functions is also quite difficult.
