At first glance, it’s just your run-of-the-mill NES cartridge, but upon closer inspection, you’ll notice that it’s been modified (some people say desecrated) to hold a 160GB hard drive. It’s certainly one of the cooler hard disk mods out there, especially since it’s Super Mario Bros 3, but there is that sense of sadness when you see that there is one less copy of Super Mario Bros 3 in this world. Maybe the owner already has a few emulators running inside the hard disk, eh?
