Recalibrating Namco Point Blank Arcade Gun: No Universal Method

There is no standard calibration menu in Namco Point Blank games. Calibration depends entirely on the cabinet hardware revision (GunCon, Namco Gun, Happ/Suzo analogs) and PCB version.

What to Try (At Your Own Risk)

1. Service Menu: Hold Service/Test button on PCB during boot → look for "Gun Calibration," "Crosshair Adjust," "IR Alignment." Navigate with Service/Test + Start buttons.
2. DIP Switches: Check PCB DIP switch chart (search "Point Blank PCB manual PDF"). Some revs have "Gun Type" or "Calibration Enable" switches.
3. Physical Adjustment: Mechanical gun pots (potentiometers) inside the gun housing – adjust X/Y offset. Requires opening gun.
4. IR/Sensor Alignment: For IR-based guns (later revs), ensure sensor bar is centered, unobstructed, correct distance.
5. Community Resources: Search KLOV (Arcade-Museum.com), ArcadeProjects, Reddit r/cade for your specific PCB (e.g., Namco System 246, System 256, GunCon2).

Safer Alternatives

• In-Game Sensitivity: Some versions have "Sight Adjustment" in test menu – adjusts software offset.
• Swap Gun: Test with a known-working gun to isolate gun vs. PCB vs. sensor.
• Hire Arcade Tech: If revenue-generating, pro calibration avoids damage.

Warning: Opening cabinet/PCB voids warranty, risks shock (CRT high voltage), and can brick the board. Document everything before touching.
