If you love playing old school games via emulators, yet you have a stack of Sega Genesis and/or Super Nintendo cartridges just sitting around gathering dust, then you might want to look into purchasing a Retrode-a USB device that allows you to play your cartridge games through any emulator, and has ports for all your old controllers.

So, you get that old school "blow on the cartridge before you slot it in" feeling, without fretting over how jacked up your old console has become over the years. Retro gamer completists rejoice!
