Optional Add-Ons

Need a link cable? I no longer sell the data link cable that connects the arduinoboy to the Gameboy, any data link cable that fits your Gameboy should work. If you want a cable that works with any Gameboy I suggest the cross-link cable from here: https://handheldlegend.com/products/2-player-link-cable-for-game-boy-original-game-boy-color-game-boy-pocket
