Dosbox Pro Controller working only partially

eberhab

Hi all,

I am successfully using a Nintendo Pro controller via bluetooth. When trying to use it with dosbox or dosbox-staging however two keys do not work:

Axis 1- (stick_0 axis 1 0)
Axis 2+ (stick_0 axis 2 1)

When opening the key mapper (Ctrl+F1) these two specific input do not trigger any reaction at all/ cannot be assigned. When defining them manually in the dosbox.map file they do not work either.

The pad fully works with other emulators/ cores and $jstest also shows that the axes fully work.

I have already considered using dosbox libretto cores, but the ones I know about are not usable for my purposes (lr-dosbox does not yet support key mapping, lr-dosbox-pure crashes on lauch with "unknown machine code").

Has anyone else had this problem?

Thanks!

More details:

RetroPie Version Used: 4.7.15
Built From: retropie-buster-4.7.1-rpi2_3.img.gz

Steps to reproduce:

Connect Nintendo Pro Controller via bluetooth
Install dosbox and/ or dosbox-staging core
Launch dosbox and/ or dosbox-staging
Press Ctrl+F1 to activate key mapper and trigger re-assigning a key
Push the left stick up or push the right stick to the right. Nothing should happen. Assigning any other key/ axis on the pad should work.

@eberhab After more research it turns out that this is a "Pro Controller" related issue which affects all cores and emulators. It has already been beautifully solved here: https://retropie.org.uk/forum/topic/16503/how-to-connect-a-switch-pro-controller-with-analog-stick-without-xboxdrv
