usbjoy adapter doesn't work in arcade mode

I've got usbjoy adapter: https://stepstick.pl/?35,en_usbjoy-a...joystick-to-pc!
This one is based on device made by Raphaël Assénat: http://www.raphnet.net/electronique/...b/index_en.php

It works in standard FS-UAE mode, but not in arcade mode (neither the menu nor during the game).
This is excerpt from arcade log file:

CONFIGURE menu STD_2BTN_USB-JOY #MENU STD_2BTN_USB-JOY
read_config std_2btn_usb_joy_8_2_0_0_windows
False
no config file found for 'STD_2BTN_USB-JOY' = std_2btn_usb_joy_8_2_0_0_windows
read_config std_2btn_usb_joy
False

Full arcade log: see attachment.

Thanks in advance for help!

Hi, have you configured the gamepad using FS-UAE Launcher settings? Please go to settings -> joysticks, and double-click on the adapter name in the list to configure it.

Yay! Problem solved, thank you very much

But why is it necessary to configure it for arcade mode, while it works in normal (launcher) mode without it?

FS-UAE itself has a fallback mode for unrecognized joysticks where "all buttons" are mapped to the fire action, and main axes and hat is used for directional movement. This is only used for plain Amiga games, where "one button" is enough.

You need a fully configured gamepad for CD32 gamepad emulation, menu navigation (where you need a primary, and a back button, etc), and Amiga games where you can use secondary fire, etc.
