Verified.

Yes, it gives the choices at the bottom of the screen (F1 for real
Falcon).  For some reason the choice text wasn't visible with yesterday
version of Hatari, but it's visible in todays version.

Tautology II still has DSP check freeze:

I tested few games that haven't worked earlier, but they
still freeze/bomb out.  Most interesting of those might
be Moongame/speeder.  Game menu animation works, but
game mouse pointer doesn't react to input.
