not used? (many false positives, but since unhide isn't implemented I don't think that exists)

This page is a work-in-progress document listing VM opcodes of the 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.
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).
|Opcode #||Name||Place of use|
|4E||o1_hideMobileCharacter||not used? (many false positives, but since unhide isn't implemented I don't think that exists)|
|92||o1_setPlayingLoop||2 times used (GRAVE.EMC, CAVEB.EMC - only used on failing copy protection, exit to DOS)|
