vJoy/PPJoy are unmaintained, so third-party virtual joysticks are out.
The XP joystick becomes a thin WDM HID minidriver (vhidmini shape,
WDK 7.1.0, x86, no signing required on XP) exposing the same Public.h
IOCTL + 25-byte report contract as the modern RioGamepad.sys, so
HidFeederJoystickSink drives both. Precedent: FASA's tasgame.sys was an
XP HID minidriver. Staged: XP app ships keyboard/lamps/plasma first,
driver as milestone 2. Win10/11 chain unchanged (ViGEm preferred).
