SETVER can make DOS look like a different version at least to a slight degree.
If I remember correctly, it tries to give the program some internals compatible
with the specified version and forces the int calls to report that version as
well. The only problem is, most of the time the reason a program only works
with _one_ and only one version of DOS is that it was designed
incorrectly--usually to take adavantage of something that was broken in that
version.
Programmers, ya can't live with 'em, ya can't shoot 'em.
