Sorry if this is a newbie question but I did try and have a scroll through the posts before asking.
I’m running the latest version of Retro Pie (donwloaded today) on a Rasberry Pi 2. I have used the SD card image and provided and outside of that have only copied roms across into the relevant directories.
My problem is that my playstation 4 controller (connected to the pi via USB cable) will work in the Retro Pi Menus but as soon as I load a game (it does not matter which emulator) the controller will not work and I have to reboot the Pi. I have setup the controller via Emulation Station and it seems to work fine in the Retro Pi Menu just not in any games…
Once in game, try disconnecting the controller and reconnect it.
I have had this happen before over Bluetooth. The fix was a clean install, i must have mucked something up in the configs from a previous version.
