G-Con2 Calibration (PS2 via Arduino USB)

This document explains how to calibrate a GunCon 2 when it is emulated or presented to a PlayStation 2 as a USB GunCon 2 device via Arduino.

⚠️ G-Con2 Calibration calibration on PS2 does not behave like PS1 GunCon calibration.
It uses a static crosshair and specific button combinations that are not shown on screen.

When Calibration Screen Appears

When the PlayStation 2 detects the Arduino as a G-Con 2 USB device, the console will automatically display the G-Con 2 calibration screen.

At this point:

  • You should see a static crosshair
  • The gun is detected, but not yet calibrated

Basic Input Test (Important)

Before calibrating:

  1. Press the trigger
  2. You should hear a gunshot sound

✅ This confirms:

  • USB communication is working
  • Trigger input is detected

If you do not hear a gunshot, calibration will not work.

Entering Calibration Mode (G-Con-2 Calibration Screen on PS2)

G-Con 2 calibration is not automatic.

To enable actual screen tracking:

  1. Hold D‑Pad DOWN for 3 seconds
  2. While still holding down press the trigger

This enables live tracking mode.

⚠️ This is required even though the screen does not visually change.

Static Crosshair Behavior (Expected)

Unlike PS1:

  • The crosshair does not move
  • The calibration screen does not update dynamically
  • This is normal behavior for GunCon 2

Do not wait for the crosshair to follow the gun.

If Your Gun Is Already Calibrated

If calibration data already exists:

  • Press either side button on the gun
  • The system will continue past calibration

No further action is required.

Performing Calibration (Sinden Lightgun Global Calibration)

If calibration is required:

  1. Hold the trigger
  2. Press LEFT on the D‑Pad

This command forces calibration mode. you can monitor the output from the Sinden Lightgun Driver log on the dashboard

What you should see:

  • On the dashboard / Lightgun log, a message appears:

Entering Calibration mode

G-Con2 Calibration:
Point the lightgun at the center of the calibration screen and press the trigger
The log will say calibration complete, you can now press the side button to continue.
