So I'm trying to bind my buttons to Nestopia with my Bluetooth-connected Xbox One S controller. Every button works fine, and I can play the game with every other button, but I can't use Select or Start. In the Input Configuration when it asks for Select or Start, I can press the button as many times as I want but nothing happens. I don't think it even knows I'm pushing it. Those buttons work fine on ZSNES and other emulators, so I don't know what the problem is. I'm on Ubuntu(xfce) by the way.

Any help is appreciated.
