So this zip file contains images that are proved to load, as I assume? I am still working on some tools (for the sake of quick and easy development, written in Java) to get a meaningful output from track 11. There is no sense in trying to fix the format in MAME as long as I fail to decode that track manually.
By the way, the HFE, as I know it from the specs, only allows for one encoding of the image, with the exception of track 0 that may have another encoding for each side.
All the images in that archive load on my system: a Corcomp mini PES disk controller, HxC GoTek drive.
If someone else is using a HxC or GoTek, I’d like to see if they can validate these images working on real TI, Myarc and BwG controllers too.
