Software Release : 3.00
Date : 03-Dec-2001
- Game plays and feels a lot faster now thanks to all this.
- Switch scanning rewritten. Matrix still scanned 2 cols/ms, but all debouncing is done by exec now.
- Fixed switches not dispatching if they closed and opened before exec had a chance to process them.
- Sound system bugs, particularly related to followup %age, fixed.
- Added statistical analysis of switch closures, which allows detection of both hyper- and hyposensitive switches. It also allows software compensation for broken switches, based on legal opinion.
- Reorganized adjustments and resets. Adjustments that weren't really adjustments are gone now, with the exception of custom message and the pricing editor.
- Added Portals 'Installs' menu, which will affect a number of adjustments without needing to reset audits.
- Duty-cycling for all coils implemented. Duty updated every 2ms with resolution as low as 1/16.

- Added controlled lamp duty cycling!
- Fixed an ancient Roll'n'Win LEFF bug that would scrawl.
- Added grace-grace periods for multiballs.
- Retimed a bunch of events with the newer faster system.
- Finally did Instant Info.
- Added coindoor ballsaver feature and adjustment. Currently, the game must be on free play for this adjustment to work, but this will likely change in the future. This adjustment, when enabled, will ballsave any balls that are currently in-play for 2 seconds per ball, UNLESS the ball save timer is already longer than that (in which case the timer is unchanged) when the coin door is opened. Balls are then relaunched when the coin door is closed again. If the game is in Tournament Mode, then this behavior will ALWAYS occur, regardless of the setting of this adjustment and the free play adjustment.
- Added adjustment for flipper button ball launching. This is intended primarily for disabled people; valid settings are LEFT FLIPPER, RIGHT FLIPPER, EITHER FLIPPER, BOTH FLIPPERS, DISABLED (default). It specifies which flipper button(s) will autolaunch the ball when the game is waiting for the player to plunge the ball.
- Added non-valid-playfield ball search.
- Now check the shooter groove when playfield goes valid, and fire kicker if ball is there.
- Added game start ball search, though it is probably pretty rare that it will actually occur because powerup ball search and in-game ball search both correct the current balls-installed count.
- Added total pages for every multiball and super mode.
- Flipper button debouncing and dispatching totally rewritten.
- Fixed replay level adjustment display bug.
