We have just published Release 3 of Ozmoo, the free Z-code/Infocom interpreter for the C64. Compared to Release 2, which came out in June 2019, this release has:
Darkmode - a secondary, configurable, colour scheme (Player hits F1 key to toggle).
A configurable splash screen just before the game starts.
Support for four new languages. Apart from English, Ozmoo now supports Italian, Danish, Spanish, French, German and Swedish.

There is a full presentation of the project on the homepage at GitHub - johanberntsson/ozmoo: A Z-machine interpreter for the Commodore 64 and similar computers
The easiest way to use Ozmoo to build games for playing on a C64 or emulator is by going to Ozmoo Online: Ozmoo Online . This web page has received many enhancements as well.
Merry christmas, Ozmoo Release 5 is out!

- Support for Plus/4 (+ C16 w/ 64K)
- Support for Beyond Zork on C64, C128 and Plus/4
- Progress bars while the game loads data into REU or RAM
- Better control over preloading (parts of the story which are loaded before the game starts, to get less pauses for disk access during gameplay)

Steve Flintham has done an amazing job of porting our Z-code interpreter Ozmoo to Acorn computers. Ozmoo for Acorn supports various Acorn computers, a co-processor, sideways RAM, shadow RAM, multiple screen modes… Impressive stuff!

Ozmoo Release 7 is out!
Ozmoo, as you may know, is a Z-code interpreter, originally written for the Commodore 64. In December 2020 we announced support for C128 and Plus/4, and there is also a version for Acorn/BBC.
Big news: You can now build games for the MEGA65! (Porting credits: Paul Gardner-Stephen)

Picture: Ozmoo 7 live on a MEGA65 devkit.
We have just released Ozmoo 8, our Z-code interpreter for Commodore 64, 128, Plus/4 and MEGA65.
The biggest news: Optimizations to make Ozmoo crazy fast on MEGA65, meaning you can definitely play large Infocom and Inform 6 games.
Note: Some large games have too much dynamic memory and can’t be played for that reason, and Inform 7 games are still out of the question.
