So having had a bit of a sort out I came across my Steelseries Free mini bluetooth controller I used to use on my Nexus 7/phone.
I’ve checked it still works by pairing it up to my pc and all is good.
Now I’m curious whether this would work with RetroPie.
I have had a PS3 pad working (after a great deal of faff) wireless with RetroPie but from my extremely limited Pi knowledge I think it was because PS3 controller drivers are already provided.
Has anyone on here got a non-PS3 or XB360 controller working wirelessly with RetroPie and what would I have to do to to make this one work?
