While you probably wouldn’t want to do this yourself (it certainly doesn’t look comfortable!), one Japanese gamer apparently forced the recently released 3DS XL on the Circle Pad Pro and got it to recognise the larger 3DS — which makes sense!
It sure has been a week for twin-thumbstick portable gaming. In addition to the PlayStation Vita (which has two thumbsticks built in), I’ve been playing around the the “Circle Pad Pro” attachment for the Nintendo 3DS.
