use a usb controller for snesx9 emulator for mac

Just a heads up, the first time you launch Sixaxis, it will prompt you to set it as an imput type along with the keyboard. Start the Sixaxis Controller service by hitting 'start' and then press the PS button on your controller and it will sync. On your PC, in the Sixpair tool, enter the address listed in Sixaxis Controller, then set it for your controller. You can change this if you like, but there's no need to do so. On your Android device, launch Sixaxis Controller, and you'll see the bluetooth address at the bottom. Plug your controller into the PC's USB port, run sixpair.

Use the link relevant to your OS, it's available for Windows, Linux, and Mac. With Bluetooth wireless: Root is required. I don't know where I can find some good information on this. Some people say that you need an app to pair it and others say you don't. Some people say it requires root access and others say it doesn't.

I've seen some things online about connecting a ps3 controller using bluetooth or wired with an OTG adaptor cable.
