Retro gaming projects on Kickstarter are pretty common, but here's one that's a bit different: a game cartridge that, when plugged into the original Nintendo Entertainment System, plays an 8-bit game, and when plugged into a Mac or PC (via USB) plays a modern version of the same game. Perhaps the coolest aspect is that the two versions will interact with each other; an ability or weapon unlocked in one is available to futz with in its cousin. That is, if the project's Kickstarter is funded, of course. As Mystic Searches' project lead Joe Granato IV tells it, the concept comes from a design document he drew up, quite literally, as a seven year-old back in the '80s.
