I have one of these picture. I am running the latest image of RetroPie on a raspberry pi 2b. I plug this thing and it is detected as a generic xbox 360 controller. I go through the setup but it doesn’t have a dpad. I have tried to set the dpad as buttons and the stick as the left analog stick, I have tried setting it up twice and manually copying in settings to the es_input.cfg file in ~/.emulationstation/ directory. Most of the stuff I have found online seems out of date because it looks the file locations have changed. No matter what I do I can not get MAME to recognize the stick. If I plug in my PS4 controller no problems. I have 48 hours to decide if I am going to keep this controller or I am out $80. Can anyone help me out?
