[Driver] mk_arcade_joystick_rpi GPIO Driver

[Porcinus]

I totally understand

I have think at some point at the beginning of the program to allow user to remake only the Analog or GPIO part and then update the existing config but I am not good at all when it come to parse text in C/C++

Edit : When speaking with Hipcat, he told me that there was some troubles with start/select (not 100% sure).
