Default PC Keybinds for Common R1 Actions

How to Check / Remap

1. Pause → Options → Controller Setup → Redefine Controls
2. Scroll to action (e.g., "Target," "Fire," "Handbrake")
3. Press desired key/button
4. Supports: Keyboard, Mouse, DirectInput controllers (Logitech, etc.)

Using a Controller on PC

• XInput (Xbox 360/One/Series): Works via x360ce wrapper (game is DirectInput native).
• DirectInput (Logitech, PS2 adapter): Native support — map R1 to "Fire" or "Target" in-game.
• Steam Input: Add as non-Steam game → use "Gamepad" template → map R1 (RB) as needed.

If you're following a PS2 guide, translate: R1 = RMB (aim), L1 = LMB (fire) typically. Check in-game control menu for your exact setup.
