New description:

 When starting the game Mystery House, there is a slight flicker before the
 first room is displayed. This is a title screen that I never even realized
 was there:

 You can see it for yourself by adding this patch:

 {{{

 +               _display->scrollUp();

         stream.reset(_files->createReadStream(IDS_HR1_EXE_1));

         _display->renderGraphics();
 +       delay(3000);

         _display->setMode(Display::kModeMixed);
 }}}

 So perhaps we should add a delay here? But there are so many versions of
 the game that I'm hesitant to even make this a pull request. I've only
 been able to test it with the Public Domain version. There's one included
 in the Roberta Williams Anthology. Another one can be found in the IF
 Archive at http://www.ifarchive.org/indexes/if-archive/games/appleII/
 though you have to change the name of the file from mystery.dsk to
 mysthous.dsk for ScummVM to recognize it.
