  • Ozmoo now supports the Commander X16 as a target

Ozmoo is a Z-code interpreter for the Commodore 64, 128, Plus/4, the MEGA65 and the Commander X16. You can use this page to build the interpreter and bundle it with a game. You can upload any story file you like, or you can pick one of the story files which are always available in the dropdown list under "Build game". Ozmoo can build games with sound for the MEGA65, but Ozmoo Online lacks the interface for this. We have prepared an archive for download, containing MEGA65 builds of the two games that Infocom released with sound: The Lurking Horror and Sherlock.
