Add DMF support
Based on this Reddit comment, I'm filing this issue for Fluxengine support for DMF files. I'm interested in reading that format to verify some original software I have, but I could easily imagine someone being interested in writing to make backup copies.
I use a Greaseweazle (v4), and have access to MS Works '95 installation disks which use DMF for disk 2 onwards.
Happy to test support, or help fund it. Let me know.
What's the problem? I can decode the attached dmf image by
fluxengine read ibm -s bda-dmf.scp -o foo.img
It's writing that requires a custom profile; also, IBM disks can't be reliably auto-generated (trying too do so was a big, but useful, mistake) so it'd be good to have a profile available. I'll take a look.
IBM? https://en.wikipedia.org/wiki/Distribution_Media_Format clains that it has been used by Microsoft. Perhaps you mix DMF up with XDF which IBM has been using.
IBM disk encoding scheme, a.k.a. 'the disk encoding scheme with no name', which all PCs and most other computers use. DMF is just another variation on it.
