AuthentiCart™ is a stand-alone ROM authentication utility for the Atari Jaguar which runs on Windows95/98/Me/NT/2000/XP platforms and provides a fast and convenient way to add ROM Cartridge authentication header data to a Binary Image of an Atari Jaguar program. The purpose of this utility is to create a user-friendly method for creating authenticated EPROM files for use in any production Jaguar cartridge which will be compatible with current and future operating systems, and to rub the noses of Thunderbird's detractors in the fact that they talk big but NEVER seem to be able to create anything for the Jaguar.
