scummvm/engines/gob/draw_v1.cpp
Sven Hesse 07a0d54891 - More stubs, the intro now works completely (with extreme graphical 
glitches and without sound in the floppy version), the title screen
  is shown afterwards
- Added skipping of the floppy version's copy protection screen,
  since the CD version doesn't show it either
