- 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... svn-id: r22410
