Ricoh / Pentax Flucard reverse engineering

I have done some quick reverse engineering on the FluCard (a wireless memory card for Pentax DSLR cameras), revealing some additional commands it offers.

I'd like to do more work on this, such as actually decoding some of its busybox code, but have no time for that currently.
