Sega Genesis Console Cartridge Backup System

In 1994 I developed a Sega Genesis console cartridge copier. The prototype system was based on the Intel 8088 CPU, 256K of flash ram for program storage, 2k of virtual memory for accessing cartridges, and a custom 4MB flash memory based reusable backup cartridge. The system also interfaced to the PC through the parallel port. I designed two units, one working unit based on the 8088, and one prototype based on the Motorola 68000 CPU.

Unfortunately, the system was never developed into a commercial device. Why? Because making backup copies of software you purchase is illegal, right? Wrong. But our lawyers thought we would get sued by Sega anyway. Sure we could claim Fair Use, but did we have millions for legal help? Nope. Today, the DMCA would definately make this type of device illegal. In fact, there's a good chance I'm in violation of the DMCA right now, simply for publishing this information.
