| 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. |
