Free Play, Coin-Up, and Top 10 Score Saving
Free Play allows Discs of Tron to start without inserting coins while retaining traditional Coin-Up operation when desired.
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 scores.
Backup and Restore support allows stored score data to be backed up and restored later for service work, events, parties, route use, or tournament preparation.
Attract Sounds, DIP Settings, and Operator Options
Attract sounds can be adjusted to 25%, 50%, or 100% of the attract cycle, allowing the cabinet to be configured for home arcade, route, event, or collection use.
On-screen DIP settings allow supported options to be configured directly from the menu system instead of relying only on physical DIP-switch access.
Supported options include bonus-life settings at 10k, 20k, 40k, or 80k and 2- or 3-initial entry. Separate score tables are available for 2, 3, 4, or 5 lives.
ROM Saver, Stealth Mode, and Cabinet Support
ROM Saver support allows designated original program ROMs to be removed when the kit is installed as directed in the Discs of Tron installation guide.
Stealth Mode allows menu access by holding Player 1 Start during power-up. This helps keep normal cabinet startup behavior cleaner while still allowing operator access to supported settings.
Upright and cocktail cabinet configurations are supported when used with documented compatible original Discs of Tron arcade hardware.
