SharkWire Online is a specialized GameShark device for Nintendo 64 with a serial port and modem added, accompanied by a now-defunct dialup Internet portal service. Launched in January 2000, it was sold only in the US. It was made by InterAct which is most famous for its GameShark and Dexdrive. This unlicensed platform was the only Nintendo 64 online service to have been released other than Nintendo's official Randnet service which had already been released only in Japan in December 1999.
