The Doctor V64 came out in 1996 and soon dominated the market by the end of the year, facing virtually no competition. Many third party developers used the V64 in leiu of the PC64 Development Kit sold by Nintendo because of its much lower cost. Recently, individuals have been using the V64 for video game piracy.
