Timo Zuccarello : winebus: Optionally split joysticks with more than 6 axes.
Module: wine Branch: master Commit: de280569a1d05905d9bd1abd89526aecf4dd3e81 URL: https://source.winehq.org/git/wine.git/?a=commit;h=de280569a1d05905d9bd1abd8... Author: Timo Zuccarello <timo(a)zuccarello.eu> Date: Thu Jun 2 23:00:40 2022 +0200 winebus: Optionally split joysticks with more than 6 axes. Add registry option "Split Controllers" and optionally split joysticks with more than 6 axes to improve compatibility with applications that do not support more than 6 axes where on Windows a driver would be installed that splits the device.
