Controller problems on Batocera

[hera]

Hi, I have 3 problems when playing gzdoom on my bartop arcade cabinet emulator that runs Batocera:
- Everytime I open doom, the controller support just disables itself, and I have to enable it everytime I want to play
- Doom recognizes all of my two joysticks but they act the same way: it is not possible to assign a certain key to the second joystick because, for the game, the first and the second joystick are the same one
- I don't think this is a gzdoom problem but I'll ask anyway: is there a way to disable joystick acceleration? I find very hard to aim because for a split second the joystick sens is really low, but then suddenly it spikes up.
If I have to specify some infos there's no problem, let me know
