Older games that rely on the WinMM Joystick functionality such as Jazz Jackrabbit 2 will ignore Steam Input controller configs completely, and the game will accept input even when the Steam Overlay is open. Tested with an Xbox One controller and a DualShock 4, both wired.

The reason why this happens is because dlls/winejoystick.drv/joystick_linux.c still relies on reading joysticks through /dev/input/jsX. The current workaround is to delete C:\Windows\SysWOW64\winejoystick.drv, however, doing that makes local multiplayer impossible.

The real fix would be to reimplement joystick_linux.c using SDL2 instead of the legacy Linux joystick API, which would allow for proper local multiplayer in games like this.

In Wine 7.0-rc1 winejoystick.drv has been removed.

Joystick APIs are implemented on top of dinput.

I don't know when this would arrive in Proton..
