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. TTFN - Guy
