Sad.  :-(

That probably means it won’t work with the 3174 either.

It sounds like they’re not doing bit level capture/replay but actually trying
to emulate the actual format (ie knowing about how sectors and addressing
are laid out).  It make the end result (ie what’s on the SD card) a bit more
usable but it also makes the emulation dependent upon what controller is
being used.
