Jacob just shared a new project: "RetroPie in a Cartridge"
For $50 and some dedication a retro gaming console can be yours and with HDMI you can play it with any modern TV or monitor. Instead of using bulky and space taking cartridges and discs it’s all on the console.
For this build, we’re going to use Retropie, an awesome software package that handles all your emulation needs with inbuilt Bluetooth and wireless needs.
Any Pi can run RetroPie, but I recommend using the Raspberry Pi Zero W as these will maximize space and be able to play all games up to but not including N64 but also has Bluetooth for all Bluetooth controllers.
