Got it now, it only took the market a little while to show the new version.
I deleted the fpse data with titanium backup just to make sure there were no leftovers from previous settings.
- disable does not work (no change to previous version)
When sliding out the game pad on the Xperia play, digital directional cross and triangle-circle-cross-square are ticked by default.
unticking all the buttons in the "Set overlay buttons"-setting disables the overlay gamepad. (no change to previous version)
When enabling the L1 and R1 in "Set overlay buttons", L2 and R2 are shown and functional.
Thats the first thing I checked and it's no biggy as long you are aware of how to fix it in the settings.
