Upgrade Original Namco Galaga 3 / Gaplus Hardware

This kit adds modern score-saving, Free Play, menu, and optional networking features while continuing to operate the original Namco arcade PCB.

Original control input, video generation, sound hardware, board timing, and game behavior remain part of the original arcade system.

Battery-Free Storage

Uses serial EEPROM storage rather than batteries or NVRAM for supported saved-score data.

16 Separate Score Tables

Maintains individual supported score tables across difficulty and lives-setting combinations.

Backup & Restore

Back up and restore supported saved score data through the kit menu.

Free Play

Play without inserting coins when Free Play is enabled.

Traditional Coin-Up

Continue using normal coin operation when Free Play is disabled.

Attract Sounds, Screen Saver, and Menu Settings

  • Attract sounds: Enable supported sound during attract operation.
  • Attract-mode screen saver: Helps reduce long periods of static imagery during idle operation.
  • Menu-driven DIP settings: Adjust supported game and operator settings through the on-screen menu.

Galaga 3 / Gaplus PCB Installation

The current installation guide documents a single 6809E daughtercard installation on compatible original Galaga 3 / Gaplus PCB hardware.

1. Verify the Original PCB Is Working

Confirm that the original Galaga 3 / Gaplus arcade PCB is fully operational before installing the kit.

2. Power Off and Remove the PCB

Disconnect cabinet power, remove the board safely, label all connectors, and record their orientation before installation.

3. Locate the 6809E

Identify the original 6809E processor shown in the current installation guide.

4. Remove the Original 6809E

Carefully remove the 6809E from its original socket and retain the processor for installation on the HighScoreSaves daughterboard.

5. Install the 6809E on the Daughterboard

Install the processor on the kit while carefully maintaining correct Pin 1 orientation.

6. Install the Completed Daughterboard

Install the completed HighScoreSaves daughterboard into the original 6809E socket and verify alignment before powering the cabinet.

Program ROM Removal Is Optional

The current installation guide states that the documented original program ROMs may be removed when using ROM Saver.

If you choose to leave the program ROMs installed, the guide shows that a spacer can be used to provide the necessary daughterboard clearance. Do not remove unrelated ROMs or components.

Standard and Wi-Fi Enabled Galaga 3 / Gaplus Kits

Standard Kit Saves supported scores, settings, and configuration data locally. No internet connection is required for gameplay, Free Play, menu operation, or local score saving.
Wi-Fi Enabled Kit Includes the same local features and additionally supports qualifying online score submission to the HighScoreSaves leaderboard platform.

Wi-Fi can be disabled without affecting Galaga 3 / Gaplus gameplay, Free Play, local score saving, score tables, ROM Saver, or supported menu settings.
