Stumbled across this the other day. Ozmoo is a new open source z-machine interpreter for the Commodore 64. It's a neat project that has a lot of potential for taking new games to old hardware.

Quoting the site:
Quote:
We were looking for a redistributable interpreter of Infocom and Inform games that could be used for new interactive fiction works on the C64.

While the old Infocom interpreters are still available, the license situation is not clear so it is risky to use in new work, especially commercial. Furthermore, some of the newer Inform-based games use features which the old Infocom interpreters on the C64 can't handle.

There are some other implementations, but they have their limitations:
  • Infocom64 is based on assembly code of the original Infocom interpreter so it has the same license issues. Also, it only works with certain setups of hardware or emulation.
  • Zeugma requires an REU (Ram Expansion Unit) and doesn't support save and restore.


I had to hack a bit at the make.rb file to get it to work under Linux. You can grab my fork here if you can't wait for the main branch to check and merge my changes.

You'll also need the acme cross-assemler and exomizer.

How I got it running under Linux:

Of course, just as the main README says, you'll need ruby and vice:

Code:
sudo apt-get install ruby
sudo apt-get install vice


Spoiler: show
First, I modified make.rb, so you'll have to grab my modded fork:

Code:
git clone https://github.com/howtophil/ozmoo.git


My changes have now been merged with the main source, so grab that instead:

Code:
git clone https://github.com/johanberntsson/ozmoo.git


Then change into the ozmoo directory, clone the acme assembler source, and make acme:

Code:
cd ozmoo
git clone https://github.com/meonwax/acme.git
cd acme/src
make


I find it easier to leave acme in place as a subdirectory, so mod the make.rb file and set

Code:
$ACME = "acme/src/acme"


Then download exomizer, extract it into an exomizer subdirectory, and make exomizer:
Code:
mkdir exomizer
cd exomizer
wget https://bitbucket.org/magli143/exomizer/wiki/downloads/exomizer-3.0.1.zip
unzip exomizer-3.0.1.zip
cd src
make


At this point you should be able to turn a z[3,4,5,8] file into a .d64 Commodore 64 diskette image from the top level of your ozmoo directory:
Code:
ruby make.rb game.z5

You'll also need build-essential, if you don't already have it.

Code:
sudo apt-get install build-essential


And whatever other requirements to build that acme and exomizer list in their documentation.
