scummvm/engines/gob/game_v2.cpp
Sven Hesse 42e03bd707 - Sound! Still a bit glitchy, though: 
- Negative frequences?!? Maybe "SFX"?
  - No sound for a small part of the intro
    (there aren't any sndKeys covering that part either)
  - A rythm-instrument (hi-hat?) in the titlemusic isn't played as one
- More differences in the drawing functions fleshed out
- Some of the goblin handling functions written
- More unnamed functions and variables, wheeee...
