ARAnyM writes in byte-swapped order by default, to enable some sort
of optimisations. When dd(1)ing onto IDE/CF discs used by real hardware
Ataris, you do *not* need to byte-swap from x86, but you *do* need to
byte-swap relative to standard ARAnyM disc images. (Or enable swapping
in ARAnyM… disable really, but that means to enable its option.)

Took me some time to figure this out, but in the end, we had it.

The same applies for floppy discs in ARAnyM vs. real x86/Atari HW.
