Okay so update. I tried to install the emulator manually, and that did not seem to work. So I updated via the Retropie Setup. I am now able to start the PS2 Emulator and I can play games via the keyboard. However the Emulator will not let me set my OG Xbox controller.

Any ideas? I am guessing there is a config file that I could edit by hand if I have to. Not so sure as to why this is giving me so many issues. Any help would be great.
