Played a little bit with my Samsung Galaxy S3:
When swiping Games up it toggles the emulators. (Req. Nova Launcher)
Got almost ALL emulators FPS optimized.
And the PS3 Sixaxis Controller works fine with them all
I made a little package with the PS3 Icons and the Wave Live Wallpaper (PS Galaxy) if you are interested:
Launcher & Package:
