The introduction in original simon1dos and simon1talkie
showed Simon's room and Simon climbing the ladder in
the lower half of the screen. The Windows version of
game actually changed the introduction to move these
two sections of introduction to the upper half of screen.
The problem can be fixed by three changes:
Setting num_line to 200 in set_video_mode_internal()
Clearing the same amount of lines in vc_62_palette_thing
()
Not subtracing _video_windows[16/17] from offs/offs2 in
vc_10_draw()
But I'm not sure how to restrict those changes to this
section of introduction only.
As far as I can tell from simon1dos disasm., those
changes seemed to be trigged by a different
_video_palette_mode value (Under 10 and not 3 or 4) for
these two sections but _video_palette_mode always has
a value of 4 in this section under ScummVM.
