tbh i only ever heard one story of a "fake" gateway card (i.e the shorter pin model) and tbh im somewhat skeptical that it even was a fake, it worked with the official gateway FW versions 1.0-2.0b2, but the user couldnt run the FPGA update on 2.1+.......if there was fakes branded as gateway card im sure we would of seen many more of them by now....one card really
........my "theory" is the card was genuine but there was a manufacturing error meaning one of the terminals was too short which meant the FPGA couldnt be updated......as i say just a theory, but i doubt if someone had made a clone that worked with the official gateway FW, they would of been churning them out like nobodies business,
but im pretty sure the black vs dark blue coloring varies between batches, especially considering they switch manufacturers a while back
