Bluetooth controller?

[mac48045]

Can a PS4 or any other Bluetooth controller be connected as a way to add a second or third player?

It could be done but configuration would be needed. Possibly as little config as setting it up in the emulators, maybe something extra to get the controller working at a system level, depending on what is it (sorry I've never attached a bluetooth controller to a Pi before so I'm not sure what may be involved).
