DIY QuickDisk-emulator for MZ-800

Geir Øyvind has written an article about his MZ-800 QuickDisk-emulator on the website:

Very good.
Does this version read or / and write to a file in dsk (cpc) format?

Not sure what you mean, are you asking if the emulator can "mount" DSK-files and allow the MZ to access files within such a disk image? I can't see anything in the sources for the QD-emulator that allows this.

I have not looked at the sources yet, I should have started with that.
Theoretically, there should be no limit to embedding read / write files in dsk format in the QD emulator.

I think the image are probably mzq (a format close to the image inside QD) but I may be wrong.

The only way to do that would be for the emulator to treat DSK images as virtual QuickDisks, like it does with directories (on the SD-card) today. But I'm not sure why one would want to do this.

The fact that MZ-800 is able to read/write QD through its ROM (unlike MZ-700) may a good indication that it should be possible if the emulated QD controller handles all the possibilities given by the Z8440 registers. A look at the arduino file shows there is that function "qdisk_write_byte_into_drive" and the contents seem to indicate that we can write in the image or in a mzf file of a virtual QD (folder).
