AFAIK nobody is currently working on that topic. So the answer is
likely "no".

There is no official way to detect Hatari (unless you enabled the
natfeats which are off by default), and it would also be a bad idea to
add such a check - otherwise your demo also won't work in Hatari once
the Videl timings have been improved.

I'd either write a big fat warning in your README.TXT file, or if you
really need a check: Install a VBL handler that increments a variable,
then wait for a second (e.g. using Timer-C during your title screen),
then check the counter. If it is less than 59, the machine certainly
does not provide the right timings.
