Retrode is a USB adapter that lets you play vintage video games, such as Super Nintendo and Sega Genesis, using the original game cartridges and controllers, on your PC or Mac.
The device is a cartridge reader that can play ROM images and saved files off your cartridge.
Users just need to find and install an emulator, plug in their cartridge, connect the controllers (optional), connect Retrode to the computer, load the ROM into the emulator, configure the controllers, and play!
Retrode would be available from 23 January 2012, costs US$84.99.
