Joystick Input

Is your feature request related to a problem? Please describe. One of the best features introduced in Diablo III (and beyond) was support for joystick controllers. I was curious if OpenDiablo would be open to such a feature?

Describe the solution you'd like A couple years ago, I developed a cross-platform HIDAPI support package for Go to tackle a private project, but I've been wondering if it could be suitable for adding joystick support to OpenDiablo2: https://github.com/sstallion/go-hid

Describe alternatives you've considered I suppose I could stock up on PS2 IntelliMouse's and relive 2000 again :-)

Additional context I've been looking for an excuse to dip my toe in OpenDiablo2 development, I thought this might be a good task to get started.
