I finished work on Haumea, the Arcturus standard interpreter for Amstrad CPC. The screenshots show it running in CPC’s system theme but it has full capability for Z-machine colors. It prompts you at the beginning when a story file uses them and whether you want to apply Z-machine colors or not. This is the way Infocom did it with their DOS interpreter.
Clarification: Arcturus standard interpreter means: Z-machine 1.1 standard compliant interpreter with arc_image support.
I am also working on a bunch of other interpreters, and updates on my existing ones. All sources are going to be released soon and Haumea will become available. I am currently holding back the release since I am finalising the release of Hibernated 2 and the file was heavily used in the repository to test the interpreter from milestone to milestone. Among other testfiles of course. Full support of accented characters, full pass of TerpEtude and CZECH.
