The button prompts are meant to switch to whatever you're using but I only implemented xbox glyphs for now, tell me if your controller is some weird binglebonkus you want supporting or else I'm just gonna go with the kbm/xbox/ps/nintendo set.
I do not have the Mad Catz Little Brother controller, just a standard Xbox One one. I did see the initial right stick one changed but didn't see anything else change.
