The volume keys wanted a partner, and the bass trim could not be one as it stood: it scaled the sample data as it loaded, so by the time anyone pressed a key the audio was already sitting in OpenAL buffers and nothing short of a restart would move it. So the trim is now a per-zone gain applied in the mix instead. Each buffer's depth - how much of the low band it occupies - is still worked out once at load from its playback rate, but the trim itself is read every frame, which is what lets Home and End move it while sounds are playing. It is the better form regardless: no rewriting of sample data, and no quantisation on top of audio that has already been through one gain stage. Home raises, End lowers, in steps of 0.05, and the setting is written to bass.cfg beside the exe exactly as the volume writes volume.cfg. Together with PageUp and PageDown that is the amplifier and the crossover the cabinets had in hardware and a desktop does not. Builds clean, runs, and neither knob fires unprompted.

The config buttons (0x37/0x36) are the first two buttons of the
Upper Right MFD's top row, reachable from the keyboard on 9 and 0.
Start and Back ship unbound so you can put anything there; the
commented lines in bindings.txt show how.

Panel buttons — the letter and number rows
The rest of the keyboard is the pod's button board, laid out as it is printed on the panel. Each MFD has 8 buttons (a 4-wide top row and a 4-wide bottom row); the keyboard rows run left to right across the three upper MFDs, then the two lower ones.

G and B are deliberately unbound: they are the physical gap between the Lower Left and Lower Right MFD clusters on the real board.
Every one of these buttons is also clickable on screen — the red strips around each MFD and the amber strips beside the map are the same addresses, and they light up when the game commands their lamps.
Volume and bass
| Key | Does |
|---|---|
Page Up / Page Down |
master volume, in steps of 0.05 from silent to 2.0 |
Home / End |
bass, in steps of 0.05 from as-authored down to none |
Both take effect as you press them, including on sounds already playing,
and both are written beside the exe as you change them — volume.cfg and
bass.cfg — so they stay where you left them. RP412AUDIOVOLUME and
RP412AUDIOBASS in environ.ini set where a machine starts out before
anyone touches the keys; delete the matching .cfg to go back to them.
The cabinets had neither control. They ran the game at unity and left level and tone to an external amplifier and a 3-way crossover, so these keys are standing in for hardware the arcade had and you do not: Page Up/Down is the amplifier, Home/End is the crossover's low band. See SOUND.md.
Not bound by default
The pilot keypad (0x50–0x5F) and external operator keypad
(0x60–0x6F) have no keys assigned — the game never reads them. They
remain bindable if you want them (they arrive as arcade RIO key events).
RGB keyboard lighting
If the machine has a Dynamic Lighting keyboard, bound panel keys mirror
the pod's lamps: red for the MFD banks, amber/yellow for the Secondary
and Screen columns, blinking in step with the on-screen buttons.
Unbound keys go dark. Set RP412KEYLIGHT=0 in environ.ini to switch
it off.
Flight sticks, HOTAS and rudder pedals
Anything that is not an Xbox-class pad — a flight stick, a HOTAS
throttle, a twist grip, rudder pedals, a wheel — comes in through
DirectInput rather than XInput, and needs to be told which axis is
which. Run joyconfig.bat once. It asks you to move each control in
turn, works out which device and axis you moved and which way round it
reads, and writes the joystick rows of bindings.txt. Then it carries
on into the setup screen so you can try them straight away.
It only writes its own section, between two marker lines, so anything you have edited yourself survives re-running it. Xbox-class controllers need none of this — they are the pad rows above and work out of the box.
By hand, the rows look like this:
joydev 0 T.16000M # or a bare slot number
joyaxis X axis JoystickX invert deadzone 0.08
joyaxis Y axis JoystickY invert deadzone 0.08
joyaxis RZ axis Pedals deadzone 0.08 # twist grip works both pedals
joyaxis SL0 axis Throttle deadzone 0 # a real lever owns the channel
joybutton 0 button 0x40 # trigger
joyhat 0 up button 0x42
Axis names are DirectInput's — X Y Z RX RY RZ SL0 SL1 — where a twist
grip is usually RZ and a HOTAS throttle usually Z or SL0.
Two things are worth knowing. Pedals is a signed axis that drives the
pedal pair, positive for the right pedal and negative for the left, so
one rudder bar or twist grip works both the way a foot never could. And
a joyaxis on Throttle with no rate is treated as a real lever: its
full travel is the throttle range, rather than nudging a position the
way a spring-centred pad stick has to.
Rebinding
bindings.txt sits beside the exe, written with the full default layout
and its own documentation on first run. Change a line, restart the game.
Delete the file to restore these defaults — worth doing after an update,
since an existing file is never overwritten.
Examples:
key J button 0x40 # main trigger on J as well
pad X button 0x40 # move the trigger to the X button
key NumPadAdd axis Throttle rate 0.75 # throttle on numpad +/-
key NumPadSubtract axis Throttle rate -0.75
padaxis LeftStickX axis JoystickX deadzone 0.15 # drop 'invert' to flip X
Addresses: 0x00–0x47 are the lamp buttons above, 0x50–0x6F the
keypads. Axis names: Throttle, LeftPedal, RightPedal, JoystickX,
JoystickY, Pedals. Key names follow the .NET Keys naming (A–Z, D0–D9
for the digit row, F1–F12, NumPad0–NumPad9, Up, Down,
Left, Right, Space, Return, Shift, Ctrl, Alt,
OemMinus, Oemplus, Oemcomma, OemPeriod, OemOpenBrackets,
OemCloseBrackets, …).
