+== 2007-08-03 (Friday) - Figured out most of the missing parts of the Apple IIGS sample header ==
+Finally figured out most of the missing parts of the Apple IIGS sample header (A not-so-pretty

+Look at struct IIgsSampleHeader). I had pondered whether there was some kind of an envelope in the header...
+and there is! It's actually identical to a part of the Apple IIGS instrument header. Making
+that connection was the key. Looking at the sample headers' histogram in Open Office also helped
+(I had made a Python program for gathering the data and outputting it as comma separated values
+to a text file. Open Office can import those .CSV-files so it's easy to read the data in).
+Also as a side thing I extracted the Apple IIGS AGI arrow cursor data from a screenshot and
+committed it to the trunk
+([http://scummvm.svn.sourceforge.net/viewvc/scummvm/scummvm/trunk/engines/agi/graphics.cpp?r1=28387&r2=28436 Diff]).
+Here's what the Apple IIGS AGI arrow cursor looks like on a blue background:

+On a different note I watched Assembly 2007's Oldskool Demo competition online during the night.
+Vic-20, Atari 2600 and NES demos, whee :-). The NES demo had nice speech effects for the credits.
