 No, it has not yet been fixed. Tried out the provided savegame with the
 French Amiga version of Future Wars and it surely crashed when walking to
 the left of the screen.

 ScummVM crashes in {{{FWRenderer::drawOverlays()}}} function on the
 {{{renderOverlay(it);}}} line. Visual Studio 2017 on Windows 7 64-bit said
 "Access violation reading location 0x00000000.".
 {{{
 void FWRenderer::drawOverlays() {
     ...
     Common::List<overlay>::iterator it;

     for (it = g_cine->_overlayList.begin(); it !=
 g_cine->_overlayList.end(); ++it) {
         renderOverlay(it);
     }
 }
 }}}

 So something to do with the overlay list or its iterator being
 vaporized/pointing to emptiness.
