I have one of these 8bitdo SFC30 controllers and I absolutely love it. I've used it so much over the last year and a half that I'm very likely going to buy one of their NES30 Pro controllers. I think the NES30 Pro is better suited for PSP emulation and for use with a lot of indie games I have on steam (e.g. Rogue Legacy, Binding of Isaac, Risk of Rain).
