how to get a custom built controller/joystick working with unity game?

Hi Unity Folks,
I made a game that works perfectly with an xbox 360 controller or keyboard. I’d like to build an arcade cabinet for it using two joysticks and only three buttons (its a twin stick platformer), and I’ve seen some pretty different ways to go about that online. I just got an intel nuc, so I’d be running on a pc with windows. It would be really great if I could get my custom controls to map like an xbox controller, but I’ve seen some promising kits online for $30 that seem to just plug and play and emulate a “pc gamepad”. Here is a link to what I’m talking about: usb board. It seems like I’d have to do some trial and error to figure out how unity would interpret this device. On the other hand, I’ve seen people use breadboards/teensy + arduino + custom code to emulate an xbox controller which seems, too complicated. Any ideas? Thanks!

Ey buddy!
I’m on the same page, did you try anything?
