SEGA Gun type II Input Protection Board for The House of the Dead 2

This repository contains the KiCAD project files for the Gun II Input Protection Board (GIPB), a component designed to help protect the gun sensors in The House of the Dead 2 arcade machines. The design is based on SEGA's Service Bulletin (09/10/2002), which introduced this board to prevent or minimize damage to the Gun Sense Board and LED Boards caused by connection issues.

Why?

This was done during some live events on Twitch.tv and tested for some time.

This is a must have for people using the arcade cabinet for guns on a hostile environment

OHMIC Set

📜 Description

Over time, disconnections or improper handling of the gun harnesses can lead to damage in the Gun Sense Board or LED Boards, potentially rendering the guns non-functional. SEGA introduced this Gun Input Protection Board to mitigate this issue. While it does not repair faulty hardware, it acts as a safeguard against further damage, extending the lifespan of the arcade cabinet's gun system.

  • Protects the Gun Sense Board & LED Boards from connection-related damage
  • Compatible with original HOTD2 and JPLW arcade hardware
  • Straightforward installation – integrates between the gun harness and the Gun Sense Board
  • Includes KiCAD project files for custom PCB manufacturing

🛠️ Installation Guide

1️⃣ Preparation

1- Send to manufacture the GERBER board to JLCPCB or other PCB manufacturer.

2- Get the components required, you can see here the Bill Of Materials BOM

3- Solder the components.

Gun protect board

Before installing the board, ensure that:

  • The Gun Sense Board and guns are fully functional
  • The arcade cabinet is powered off

2️⃣ Installation Steps

  1. Locate the Gun Sense Board inside the arcade machine.
  2. Disconnect the gun harnesses from the GUN1P and GUN2P ports.
  3. Take the Gun Input Protection Board (GIPB) and connect its labeled GUN1P and GUN2P connectors to the corresponding ports on the Gun Sense Board.
  4. Reconnect Player 1’s (Blue Gun) harness into GUN1P on the Protection Board.
  5. Reconnect Player 2’s (Red Gun) harness into GUN2P on the Protection Board.
  6. Secure the Protection Board using the provided spacers and screws.
  7. Power on the arcade cabinet and enter Self-Test Mode.
  8. Navigate to Gun Settings and recalibrate the guns.
