+MACRO DAT FILE By Ioncannon
+
+0x00: Unknown
+0x02: Unknown
+0x04: Size of file minux 0x20?
+0x08: Size of macro book from 0x10.
+
+After a 0x11 byte header, the macro entries begin. All macro entries
+are XOR encoded with 0x73.
+	
+Each macro entry follows this format:
+
+-Title
+-Icon
+-Key
+-Line List
+
+Each section begins with a marker (T, I, K, L), followed by two bytes (little endian) telling the size, and then the data. 
+Data seems to be always null terminated. For example: 
+
+A title: T 06 00 Greet\0
+A icon: I 08 00 001024B\0
+A key: K 04 00 005\0
+A line: L 0A 00 Well met!\0
+
+Each macro entry contains 1 title, 1 icon, 1 key, and 15 lines. All three of these entries must exist even if not used,
+with data size being 0x01 for Titles and Lines, containing an empty string ("\0"). 
+
+-Max line size is 0xB5.
+-Max lines is 15.
+-99 macros must exist, regardless if used (values are empty as above).
+-Icons are hex values to the icon table. There is a exh file called "macroicon.exh" which contains all usable icons. The key MUST equal the row number (hex) of the icon. This is how SE fixed the 
+issue of allowing icons outside this set to be used.
+
+After 99 macros, the data is padded with 0s to 0x46000. This is most likely to allow the max amount of data to be filled
+for all macros, lines, and titles.
