Access the HighScoreSaves Lost Tomb 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, Attract Sounds, and Permanent High Scores
Free Play allows Lost Tomb to start without inserting coins while retaining traditional Coin-Up operation as an available setting.
Supported score data is stored using serial EEPROM, so batteries or NVRAM are not required for saved scores. The kit stores the Top 10 supported high scores permanently.
Attract sounds can be enabled during every attract cycle, and attract mode screen cycling helps reduce the chance of CRT monitor burn-in during idle operation.
Stern Hardware, ROM Saver, and Score Tables
Lost Tomb uses original Stern arcade hardware, and this kit is designed to preserve the original maze-action gameplay, controls, timing, sound, and cabinet behavior.
ROM Saver support allows designated original program ROMs to be removed when the kit is installed as directed in the Lost Tomb installation guide. This can help reduce heat and power usage from aging original ROM hardware.
Separate score tables are supported for 3 and 5 lives settings, helping keep saved scores organized across different gameplay configurations.
Disable Continues, Disable Advertising, and Stealth Mode
Disable Continues can be useful for Free Play operation, events, tournaments, or arcade setups where continues should not be available.
Disable Advertising removes in-game advertisement screens for a cleaner cabinet presentation.
Stealth Mode provides hidden settings-menu access, helping the cabinet retain a more original-looking startup appearance.
