What game controller are you using?
I’ve made a tonne of posts and have been tearing my hair out this past couple of weeks. I’ve looked at everything from Scuf to Xbox (normal) to Steelseries Nimbus to 8bitdo and a whole bunch of other controllers.
I want something reliable, which plays well, connects easily with the iPad and which I can preferably charge at a wall safely or through the iPad and a USB hub. I really don’t want to charge through my aging PC should it stop working one of these days.
