I don't remember which pin it was, but yes, that sounds about correct. I
have such hardware modification in one PC Card slot (dip switch for
selecting normal operations or pull up for Genesis mode), but I haven't
yet had enough time to implement code for flashing in genesis mode.

That should be possible, but not with current prism2_srec/Host AP
