Krull Arcade PCB Upgrade Overview for Original Gottlieb Hardware
Review the available HighScoreSaves upgrade option for compatible original Gottlieb Krull arcade PCBs, including Free Play, high score retention, installation requirements, hardware compatibility, ROM Saver support, attract sound options, menu-driven settings, God Mode practice, and optional Wi-Fi leaderboard support.
This category is intended for collectors, operators, and restoration projects using original Krull arcade hardware. The upgrade keeps the original Gottlieb PCB in service rather than replacing the cabinet with an emulation platform, reproduction board, or multicade system.
Krull installation requires an Intel 8088-compatible processor installed in a compatible 40-pin socket. No soldering is required when the original 8088 processor location is already socketed.

Access the HighScoreSaves Krull Settings Menu
To access the settings menu, hold Player 1 Start while turning the cabinet on. Release the button when the on-screen prompt tells you to continue.
Free Play, EEPROM Score Retention, and Top Score Tracking
Free Play allows Krull to start without inserting coins while retaining optional coin operation when desired.
Supported score data is retained using battery-free EEPROM storage, so batteries are not required for local score retention.
The kit displays the Top 10 Elite scores. The Daily Top 25 scores are not retained after power is removed, so this category should be understood as a Krull Free Play and supported high-score-retention upgrade, not a full Daily Top 25 score preservation system.
Gottlieb Hardware, Attract Sounds, and ROM Saver
Krull uses original Gottlieb arcade hardware, and this kit is designed to preserve the original gameplay, timing, sound, and cabinet behavior.
Attract sounds can be configured for every intro screen set, 1 of 4, 2 of 4, or all the time. Attract mode protection helps reduce screen burn during idle operation.
ROM Saver support allows the original program ROMs to be removed because the daughterboard supplies the required game code when installed as directed.
Backup, Restore, Multiple Score Tables, and God Mode
Backup and restore support allows score data to be saved and reloaded from the settings menu for service, event preparation, or maintenance.
Multiple score tables are maintained based on the selected number of lives, helping keep score results organized across supported gameplay settings.
God Mode provides unlimited-lives practice. Scores are not saved while God Mode is active, which keeps practice sessions separate from normal score tracking.
