Hate to say it, but it’s a problem. I just picked up an Xperia Play, loaded the current May 29 Google Play Store build and I’m seeing the same behavior, the CIRCLE button works as a back button. I’m running the Gin2Blur ROM, Android 2.3.3. I saw another post in the Xperia CM9 thread where they’re having the same problem:

That said, I found the apk version you provided jpstar in April, uninstalled the May 29 Play Store copy, side-loaded the other apk, and it works fine. The keymap notices are slightly different in that version and the buttons all appear to work.

Port 1: keypad-game-zeus.

I’m glad to run any keypress tests, debug apk, or join on irc as you need. A shame Sony made the Xperia gamepad such a mess! This is a great emulator set, I’m glad I found it.
Thanks,
