@slope game said in Unnable to configure/save Guncon Buttons on PSX:

Some games like Time Crisis, Point blank, requires A or B button to play or to skip calibration screen.

If I go to Main Menu > Settings > Input > Port 1 Controls , I can set it (they all show like N/A but still working). But they wont save, I tried all possible saves in Retroarch (save on exit, save core settings, save input core....) none seems to work.

Is there anyway to save or I have to config each time I want to play?

You should ensure that you are using the right input driver. You can check this under Settings > Input > Input Driver. If you're using a driver that doesn't support saving settings, switch to a different one, like xinput or sdl2.
