ROM-Reader for Super Nintendo / Super Famicom Game Cartridges

Hi. I've been planning on building this for some time. But I already downloaded the repo back in November (the download is Cart_Reader_V27D.zip) and ordered the main PCB based on what I downloaded then. Do I have to re-order the PCBs again now, or can I go ahead and make what I have work? I just want to dump my N64 saves, as I already have ways of getting all my SNES and GBA saves. Could I build the variant listed here, and if so, how?
