Seems pretty straightforward. They hook DirectInputCreateA() and pass their own device enumeration wrapper with the offending flag removed.
The flag DIDEVTYPE_JOYSTICK was added by this fix not removed.
The idea is, rather than handle up to 8 devices, otherwise UB and usually crash, handle up to 8 "joysticks" and disregard any beyond that.
