Tune your controls

ReCarbon turns the keyboard into an Xbox 360 controller. Pick a device, a mode and a keyboard preset (WASD, Arrows); hover, tap or tab through the list to light up each control. The Garage shows ReCarbon's built-in presets only: your own profiles are made in game.

These keys and buttons are bound to Xbox controls (that part is tested), but what each does in a race isn't known yet. Nitrous, Handbrake, Speedbreaker, gear shifts, Change Camera and Look Back aren't tied to any of them yet: that waits for a hand test.

Presets and your own profiles

ReCarbon has two built-in keyboard presets. WASD, what a new player starts with, is the original layout: it drives with W A S D, and the arrow keys work the left stick (Left and Right steer too) and the D-pad at once. Arrows drives with the arrows and leaves W A S D to the D-pad; in it no key does two things. The built-ins can't be changed.

Custom profiles are configured in game, not on this site. Open Settings (F1,Fn+F1 or ⌘+,) and go to Controls with Q /E: the Keyboard Profile row switches profiles at once. Rebinding a key of a built-in preset makes a copy of it, such as “WASD (custom)”. Controller buttons are rebound on theController tab, which has its own Controller Profile row.

Profiles live in ~/Library/Application Support/ReCarbon/profiles/ (keyboard.toml andcontroller.toml). The active keyboard profile's keys are also written to the [keys]table of settings.toml, so an older ReCarbon still finds them.More on profiles

Controller notes

Tested The default mapping below is pinned by unit tests.
Automated SDL's virtual controller drives the menus, survives unplugging, and rebinds buttons in Settings > Controller. That is automated evidence, not a hardware test.
Pending No physical controller has been hand-tested with ReCarbon yet, and controller rebinding hasn't been tried on hardware. What each button does in a race is still to verify.

Default controller profile

Pads are read through SDL3 by button position. The Xbox / PlayStation switch above changes the names shown, not this mapping. Triggers, sticks and their deadzones are fixed; only the buttons can be rebound, in game.

Not mapped Back paddles, extra buttons and the Guide button aren't read by ReCarbon. If a pad's own firmware or software remaps a paddle to another button, it acts as that button: ReCarbon only sees the result.

Tested controllers

None yet: the physical controller test is deferred. A controller model is listed here only after it passes a physical hand test with ReCarbon; virtual-controller runs don't count. A listing records a test result; it is not an endorsement or a recommendation.
