Tester ask: configure non-Xbox controllers. New L4JOY layer (DI8): enumerates every non-XInput game device (up to 4), DIJOYSTATE2 polling with range normalization, reacquire-on-loss, 3s hot-plug re-enum. XInput devices are excluded via the documented RawInput IG_ VID/PID check (live-verified skipping a real XBOX360 pad -- no double-feed). bindings.txt grows joydev/joyaxis/joybutton/joyhat rows (device slots by name substring or ordinal; axes X..RZ/SL0/SL1 with invert/slew/ deadzone; hats as 4-direction buttons with diagonal chords). PadRIO runs them through the existing channel/event machinery -- per-binding edge arrays release automatically on detach (the #24 rule), and a direct throttle axis maps full lever travel onto the 0..1 channel while the gait detent still snaps a lever parked in the walk/run dead band. BT_JOYCONFIG=1 (joyconfig.bat) runs a console capture wizard: move each control when prompted (stick/twist/throttle/fire), invert derived from the move direction, hat look cluster auto-added, output written between markers in bindings.txt with the rest of the file preserved. Legacy L4DINPUT DIJoystick (L4CONTROLS=DIJOYSTICK) untouched. Verified: grammar accept/reject per line, XInput-exclusion live, 30s in-mission no-device polling clean. Awaiting a tester with real stick hardware for axis verification. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

|
|
// through DirectInput 8 (the standard generic-HID game API). It exposes
|
|
// up to BTJoyMaxDevices attached devices as normalized state blocks; the

// PadRIO poll maps them onto the pod's control channels through the

// joydev/joyaxis/joybutton/joyhat rows of bindings.txt (L4PADBINDINGS.h)
|
|
// -- the same binding machinery the XInput pad uses.
|
|

|
|
// XInput-class devices are EXCLUDED (they'd double-feed through both
|
|
// APIs): a DirectInput device whose VID/PID appears in a RawInput device
|
|
// path containing the "IG_" marker is an XInput device (the documented
|
|
// wbem-free detection).
