Retropie with a gameboy advance as controller
You have a gameboy advance. You have an amazing retropie installation. So… You have already your perfect controller…
Inside Gadgets did it!
I bought this wonderful thing on insidegadgets.com:
You plug the usb on your raspberrypi, and plug the cartridge in your game boy advance, and… it’s all: you can use it with your retropie installation :)
But it’s not cheap: about 30$ for it, and you’ll only have the game boy advance buttons: forget the psx games :s
