A new gizmo called Retrode is on the way to market that allows you to plug in your actual Sega Mega Drive and Super Nintendo cartridges and controllers, before playing them on a PC, tablet or smartphone. It seems that the USB connected device extracts the relevant ROM data onto emulation software and hey presto! Your retro games are playing on almost any device.
The fact that it's emulating the ROM from a physical cartridge in your possession is the key, and it's possible to use the device to make a back-up of your software as defined by the Copyright, Designs and Patent Act 1988, though any distribution of that back-up would be highly illegal.
It's due out on 23rd January and will set UK buyers back a little over £70. It might be on grey legal and moral ground, but what do you make of it?
