3E	o1_loadSoundFile	not used
4B	o1_specificItemInInventory	not used
4D	o1_mobileCharacterInScene	not used

-This page is a work-in-progress document listing VM opcodes of the [[kyra|Kyrandia]] games. Unless otherwise noted, these opcodes are based on Kyrandia 1. Cyx created the list of Cmd functions, clem and Lordhoto will try to fill in parameters and usage notes. If you have any additions, contact the  ScummVM team on IRC.
+This page is a reference of unused opcodes in Kyrandia 1.
-It is assumed that the opcodes stay the same during all revisions of Kyrandia. A quick comparison between English 1.0 and English 1.3 seems to support this. Generally the list is created by analysis of 1.0 script.

-Hint: To disable an opcode/command pair in the compiled scripts, overwrite it with '''4C 00''' (add sp,00).
