Ozmoo is a Z-code interpreter for the Commodore 64, 128, Plus/4, the MEGA65 and the Commander X16. It was written by Johan Berntsson and Fredrik Ramsberg, and released in 2018 under the GPL 2.0 license, meaning it can be included with games which are given away or sold. Ozmoo supports Z-code versions 1, 2, 3, 4, 5, 7 and 8.

This page uses a port of Ozmoo for Acorn/BBC computers, made by Steven Flintham.

You can use this page to build the interpreter and bundle it with a game. There is more information on the Ozmoo homepage and the Ozmoo for Acorn homepage.

Z-code files typically have names ending with .dat, .z3, .z4, .z5 or .z8. They can mainly be found in Infocom games (yes, you can grab a .dat file from say Zork 1 for MS-DOS and use it to build a version for Acorn with Ozmoo!) and on if-archive. Z-code files produced by Infocom are usually quite fast on Ozmoo. Z-code files produced by Inform 5 or Inform 6 may at least be fast enough to be fun, but it depends on how much processing they do. Z-code files produced by Inform 7 are pretty much guaranteed to be horribly slow, and they are likely to crash at some point as they need a very large stack for some operations. There is also ZILF, a modern compiler for ZIL, the language Infocom used to write their games. Z-code files produced by ZILF should typically play just fine on Ozmoo.
