Hi. I have registered just so I can make one comment.
I have Xperia Play and the O button for the actual pad hasn't been working for the last few updates. The last one that was working was 11.18 and ever since I updated from that, every new version has not been supporting the O button. Whenever I press it, it just goes to the menu. I've even tried assigning it in the configuration, but it still does not work. It only opens the menu. Every other buttons seem to work fine, but the O refuses to work. It would be great if you could fix this since the newer version seems much better, but I rather play it on the actual pad instead of the touch screen.
