Emulator

Not an issue, but something that I don't know if it is possible to implement: the analog stick of the real Nunchuk (using real Wiimote) has (in my opinion) a huge dead zone and after that too much sensititvity, so it is very difficult to walk with a character, in fact you have a very very minimun range to use for walking and then there is a lot of useless space (range) on the ananlog stick for running.
My question/request is: is it possible to implement some options of manual tweaking the Nunchuk analog stick like for example (but not limited to) the options for the joypad that emulate the Wiimote?
Thank you.
