The project is surprisingly simple. All you really need to do is crack the cartridge case and position the parts. Then it’s simply a matter of closing the thing up and plugging it back in. It doesn’t have an Internet connection but you can easily add a Wi-Fi adapter to the mix to go online.
The project uses RetroPie, the multi-platform game emulator, and is powered by a mini USB cable plugged into a power supply.
￼The basics of what I’m calling the Pi Cart (great name, eh?) involve a Raspberry Pi Zero, an old NES cartridge, a small USB hub and adapters of various sizes. Unless you want to get crafty or save a few bucks on adapters, no soldering is required.
What I’d really like to see is someone actually connecting a Raspberry Pi to an actual cartridge PCB thereby allowing you to put a new brain into an original NES. The resulting chimera might be an abomination, however, so maybe this idea is a bit better.
