Superku apparently had problems with it, though, with some buttons not being responsive.
Exactly, this is what I wrote/ experienced:
Hm the control sticks (of my PS4) controller seem to work fine but the buttons don't. Every let's say 4 seconds the input is delayed (the state of at least one button changes too slowly, it takes about one second more than with joy_1,...).
If you have not experienced this don't worry, I will try to figure this out myself or go back to the joy_ implementation.
I cannot recreate this misbehavior right now though so there may have been some mistake on my side and its implementation. However, I am not sure what could have caused such an issue (which is what throws me off of the joyGetPosEx approach right now, I'd hate to deliver a game with sporadically unresponsive controls).
