Also, another note: If you want to work with 80-track images in MAME, you must specify that you want to use an 80-track floppy drive. Or, in other words: You cannot read 80-track images with 40-track drives (surprise :-) ).mame64 geneve -peb:slot8 hfdc -peb:slot8:hfdc:f1 35dd ...
Beware - if you work with an 80-track drive in MAME, your 40-track images will become unreadable on 40-track drives once you write to them.
The safest bet is still DSDD40.
OK. One of my purposes with that 1.44 MB image was so that everything is all together in one neat little file as it exceeded DS/DD capacity.
I understand the HFDC needs to be configured in MAME and/or MESS for 80 tracks. However, how does 40 track images become unreadable? I thought they were straight sector dumps. Is sector 0 being modified of a 40 track disk to think it is in an 80 track drive or is there something being appended to the file, etc.?
Trying to understand the changes.
I understand what is going on with HFE images. Just trying to understand what is going on with the DSK images.
