I wonder if joy2key is an option? If it is it would be DEAD SIMPLE for anyone to use with I believe the ability to share the setups.
I note it has deadzones since version 5.7
I use it for many things (VPinball - zero delay circuit with home made box with leaf and arcade buttons, VirtualOn - warthog and t16000, Evochron Legacy button box - another zero delay circuit board) as buttons/switches but have not tested the gradual input of a joystick.
Not sure it even has that ability so I will test tonight 🙂

Just thinking aloud here - Even if it didn’t have that axis functionality it could be used for everything else so then once a single setup was shared ONLY the axis stuff would need to be mapped? I am intrigued by the possibility seeing as I have little faith in the TARGET software continuing to work (I have another post on this topic elsewhere).
