Access the HighScoreSaves Crazy Climber 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 and Permanent High Scores
Free Play allows Crazy Climber to start without inserting coins while retaining normal Coin-Up operation as an available setting. The kit stores the Top 5 supported high scores locally.
Supported score data is stored using serial EEPROM, so batteries and NVRAM are not required for saved scores. Backup and restore functions are included for supported score data.
Crazy Climber also supports separate score tables for 2, 3, 4, and 5 lives. This keeps supported score results organized across different gameplay configurations.
Attract Sounds, Reset Button, and Operator Settings
Supported attract sounds can be adjusted for 25%, 50%, or 100% rotation. Attract mode protection helps reduce screen burn during idle operation.
On-screen DIP settings allow supported options to be adjusted through the settings menu instead of relying only on physical switch changes.
The Reset Button option allows the game to restart using Player 1 + Player 2 when enabled. Fast Boot also reduces startup wait time.
