+ *
+ * - "Sam's Teach Yourself DirectX 7 Programming in 24 Hours"
+ * A book from 1999 - a year too new, and a DirectX version too new.
+ * - "DirectSound Wrapper Classes"
+ * https://www.codeproject.com/articles/12076/directsound-wrapper-classes
+ * Published in 2006 - 7 years too new.
+ * - "Chicken Tournament"
+ * https://github.com/shlusiak/Chicken-Tournament/blob/master/src/Resources/MMIO.h
+ * A game from 2003.
