I pulled out a box marked Hyperdrive and it has the main logic board, a little board that looks like the sound board and another pcb that has the network jack on it. It is about 4" square and what looks strange is that on the bottom is a long flat plug with about 30 pins on it and it looks like it press fits into another board or something else. I don't have any other boards in the box, am I missing something to make this game work? Is that only for linking and can I get away without using it for a single player? and does anyone know of a download link for the manual?
Thanks very much,
Russ
