I will definetelty have to do this mod. Or similar one. Got mine today and dpad is quite unusable as it is. Very hard to make diagonals, so very difficult to play fighting games. Specially the down-left diagonal is almost impossible to do.
It's a pity, because device is fine, and with a normal dpad like g5a would be better, but dpad is very poor, at least in my device.
I am not dissapointed anyway, since my main use for this device is development and just some android games, but for emulators it clearly needs a better dpad.
