Hi, good morning.
I saw a guy selling a controller, a small one player fightstick with a raspberry inside.
His controller has a usb jack in the back, with the option that when it is plugged to a pc it is recognized as an usb controller.
He does not need to to anything, it is plug and play. He claims that there is a kind of code to enable this on the raspbeerry. Here is the video, skip to 7 minutes and you will get the idea. I found others doing that, but I wish more info about what to buy. I want to be able to do it myself, as I have tons of buttons laying around and some mdf leftovers. Here is the video:
Thanks!
