It wasn't long ago that we featured the SD2IEC for your C64, in which games could be played directly off an SD card without faffing about with loading real original games. Well what if I told you there was a device out there which enables the playing of pretty much every single Sega Mega Drive, Genesis, Sega Master System and 32X game through a single cart based SD in your Mega Drive! Welcome to the Mega Everdrive, a very interesting product sent to us by RetroTowers for review.
