+Space Quest I has 26 instruments (1192 bytes), all others have 28 instruments (1292 bytes).
 of the instruments are shared between the two data sets so
 Space Quest I has 10 unique instruments. The unique instruments
 are 2, 4, 13, 14, 17, 18, 20, 21, 22, 23 (Zero-based numbering).
+Here are the starting offsets for instrument data in the tested Apple IIGS AGI executables:
+* 0x80AD
+** SQ.SYS16 (Space Quest I, AGI 1.002)
+* 0x844E
+** LL.SYS16 (Leisure Suit Larry I, AGI 1.003)
+* 0x8469
+** KQ.SYS16 (King's Quest I, AGI 1.006)
+** PQ.SYS16 (Police Quest I, AGI 1.007)
+* 0x84B7
+** KQ2.SYS16 (King's Quest II, AGI 1.013)
+** MG.SYS16  (Mixed-Up Mother Goose, AGI 1.013)
+** KQ3.SYS16 (King's Quest III, AGI 1.014)
+* 0x6563
+** SQ2.SYS16 (Space Quest II, AGI 1.014)
+* 0x8979
+** MH.SYS16 (Manhunter I, AGI 2.004)
+** KQ4.SYS16 (King's Quest IV, AGI 2.006)
+** BC.SYS16 (The Black Cauldron, AGI 3.001)
+** GR.SYS16 (Gold Rush, AGI 3.003)
+BTW I also found out that by going 4 bytes backwards from the start
+of the instrument data you'll find a little endian 16-bit
+word giving the length of the whole instrument set (So it's
+with Space Quest I, 1292 with all the others).
