+ A gamepad speaks XInput, and the game reads it without being asked.
+ Everything else — a flight stick, a HOTAS throttle, a twist grip,
+ rudder pedals, a wheel — speaks DirectInput, which names its axes
+ X Y Z RX RY RZ SL0 SL1 and says nothing about
+ what they are for. Somebody has to decide that your twist grip is
+ the rudder and that pushing it right means right. That is what
+ joyconfig.bat is.
+
+ The direction is the whole point. A stick that reads
+ positive pushed right and one that reads negative are equally common,
+ and nothing printed on the box tells you which you own. So the wizard
+ does not ask you to know — it asks you to move, and reads the
+ answer off the movement. Skip a prompt with SPACE if you
+ have no such control, ESC to abort without writing.
+
+ It writes only its own section of bindings.txt, between two
+ marker lines, so anything you have written yourself is kept — including a
+ deadzone you tuned by hand after trying it. Before it starts it prints
+ every axis at rest: a stick whose driver reports an odd range
+ shows up there as X +1.00 on an untouched
+ stick, rather than as a mystery later. Xbox-class pads are excluded from
+ all of this, so nothing ever counts twice.

| Pedals | ++ A signed axis that works the pedal pair — positive + for the right pedal, negative for the left. The pod has one + under each foot; a twist grip or rudder bar is a single control + that presses one or the other and never both, which is exactly + what this says. It is a channel name like any other, so a gamepad + stick can drive the turn with it too. + | +
|---|---|
| Throttle | ++ A joyaxis on the throttle with no + rate is treated as a real lever + and owns the channel: its full travel is the throttle + range. Spring-centred sticks have to nudge a position instead, + which is what rate does — a lever that + stays where you put it needs none of that. + | +
+ A twist grip is usually RZ; a HOTAS throttle is
+ usually Z or SL0. Set
+ RP412JOYLOG=1 to log devices as they attach and drop away.
