[request] Menu controls for bluetooth devices and xperia play

[kouta-kun]

The ability to load, save, or choose games via the d-pad and circle button would be nice. Also customising controls and circle pad support would be nice as well.

(also I do realise this is in development and my asking is mostly just to bring to attention in hopes that down the road when someone finishes up the projects they are working on they might pick up this)
