Am I the only one who doesn't really have a problem with touch screen d pads and buttons on classic emulators?
I have the 2600.emu , JohnNES, JohnGBC and JohnGBA on my android phone and on my daughter's Android tablet and they all work just fine to me. I know a bluetooth gamepad would probably feel a bit better but NOT enough for me to lug around a controller when I can use the controls right there on my screen.
Maybe I'm in the minority but I would be I am not especially when it comes to people gaming on a smartphone.
