I hacked my new old-school Commodore-sold (ArcadeR) joystick with a DB9 connector to my iPad and can play Ollie's Arcade (https://apps.apple.com/app/ollies-arcade/id6446127619?ls=1&mt=8&uo=4&at=10l4G7&ct=APPS) games with it!
This feels super awesome (although hard to film myself and play at the same time).
(The USB cable to the microcontroller that you can see here is just for power - the device is actually pretending to be a BLE wireless keyboard. đ)
