I found a major bug (possibly).
I'm using a Motorola XOOM on Android 4.1.
I'm trying to set up PS3 controllers with the Sixaxis app. I've previously been able to do this on the older version of Mupen, but you've changed the scheme for setting buttons on this version. I like the new setup but it doesn't work!
When I open the input settings, I am greeted with a nice clean screen to turn on the gamepads I want to use. Ok, cool. So I turn one on. I hit configure, pull up the controller graphic thingy, touch a button and NOTHING HAPPENS! No matter how many times I press it, I get nothing but a quick flash of blue over the button. I see nothing that says "Press a button on gamepad" or the like, and pressing a button on the PS3 Controller doesn't do anything, either.
Also a huge annoyance I foresee: The on/off button for the gamepads should stay on or off all the time. When I leave the screen or even toggle "Volume Key Controls", they all switch back off. It would be very annoying to have to switch the controllers on every time you start the app.
I've had a ton of fun with Mupen in the past and am looking forward to testing this update once I can get my controllers mapped out (and actually keep them turned on when I leave the screen!). I hope this problem can get fixed soon. Thanks for the great app!
