So this is my first time using Pi and RetroPie and I can safely say I am a noob. So I have one big problem. I am using a xin mo dual arcade controller like this one and when I start RetroPie for the first time and map the buttons, it won’t map up and left. I have the same problem with ultraslim and chameleon. It could be a xin mo problem but it works fine on PiPlay. So I don’t know what the problem is.
