Hello everybody, in this video I'm demonstrating you my controller/console made with a raspberry pi zero and a fairly cheap controller. I'm using RetroPie, of course, to play ROMs. The way I did it, the SD card is easily removable. That way I can retrieve my data and move them to another raspberry pi on another machine (an arcade machine for example), without the need to open the controller and mess up with anything.
I'm using my phone to power the pi. I didn't notice anything not working properly, but I would recommend using an adapter at 5V, 2.1A.
Tell me your opinion, and if you have any questions feel free to ask. Thanks! :D
