Detailed changes description

Reference to the revision 1.3X.

The Trunk error handling procedure has been refined to not give a false positive during normal playing conditions with a healthy Trunk mech.

With secondary function to reset the error state in case of genuine in-game Trunk error (like with a stock ball).
When tournament play selected: Opening/closing the coin door will reset the Trunk error state.

New feature adjustment A.2 21 “Spell theatre”. Options: “Easy” and “Hard”.
Easy: As rev. 1.3X. Spell theatre is lit except in the modes: Theatre, Lock multiball and Grand finale.
Hard: On THEATRE advance, the Spell theatre light will go off. Making a major shot in the game will re-light it.
Major shots considered: Trunk loop both ways, Trunk, both ramps and the right orbit. Not the left orbit nor the Tiger saw captive ball.

Adjustment “Spell theatre” defaults.
Ex. easy, easy and medium pre-sets: Easy.
Hard and ex. hard pre-sets: Hard.

New feature adjustment A.2 22 “Combo max value”. Options: 8M – 80M in 4M steps. Default: “20M”.
On combo value build-up, when it reaches this value, it will stop incrementing.
Combo scoring will proceed at this value.

New feature adjustment A.2 23 “Bonus-x adv”. Options: “1” and “2”. Default: “1”.
Bonus-x increment for each top lane completion. 1 or 2. With 2 being 1x->2x on first completion.

New feature adjustment A.2 24 “Hocus 2nd saver”. Options: “No” and “Yes”. Default: “Yes”.
In single ball play only!
If the Hocus pocus outlane saver magnet fails, a compensation one shot ball saver will serve the ball to the plunger lane.
The feature only saves balls going to an outlane, that should have been saved to an inlane.

When tournament play selected: Basement awards.
A catch-up choice that will award progress on Illusions or Clock. Which ever is lacking behind the other.
Generally:
If the clock is 10 or 11 am, Madness is awarded.
If the clock progress is less than the Illusions progress, Adv. clock is awarded.
Else Illusion is awarded.
Special cases:
Illusion is not awarded if achieved for this Grand finale, if already lit, if one is currently running or when other states where an Illusion cannot be started at the Trunk.
Adv. clock/Madness is not awarded if achieved for this Grand finale.
If Illusion is not available, Adv. Clock is awarded if not achieved for this Grand finale.
If neither is available, 20 Million is awarded.

When tournament play selected: Limited ball search. No compensation locked balls release or free multiball.

The Tiger saw motor control has been ported from the rev. 1.4H software. And slightly improved.
It runs for a solid two seconds on a captive ball hit. Instead of the very short pulse in the rev. 1.4H implementation.
In a Tiger saw mode and multiball stack, it stops when both modes are finished. And not when just the first of them finishes.
Tiger saw motor added to the solenoid test.

Feature adjustment A.2 12 “Trunk ball save” now has three options.
“No”: Trunk ball saver is disabled. This is default.
“Yes”: Rev 1.2 behaviour. Trunk ball saver is enabled for more Trunk hits.
“Once”: Rev 1.3X behaviour. Trunk ball saver is enabled for the first hit to the Trunk only.

The buy-in high scores are removed from attract mode DMD presentation and status report, when the buy-in feature is disabled.

The max bonus-x 5M is awarding 5M points.

Midnight is corrected to be at 12 AM. Not 12 PM.

Adjustment A.1 28 “Min. vol override” defaults to “Yes”.

Adjustment A.1 21 “Language” is limited to to “English”.

Note

The false positive Trunk error trap was to start choiced Illusions by hitting the Trunk while rotating. Just before it reaches the open position.
The fix does not change the way the Trunk operates. Registering shots, the movement, timing etc.

Coin door error reset is designed for competition play, where a stock ball has caused the Trunk error.
Provided that the bottom coin door interlock switch is not fixed in the closed position.
Upon closing the coin door, allow a ball search to reset the Trunk to its correct position.

Spell theatre is always lit at start-of-ball.
Spell theatre is always lit when Theatre mode, Lock multiball and Grand finale finishes.

The Hocus pocus saver compensation works when the saver mechanism is broken (proximity switch or magnet).
But, requires inlane, outlane, trough and shooter lane switches to be in shape.

The Advance clock Basement award is +3.

The Tiger saw motor runs continuously in the Tiger saw mode and multiball.
And it is pulsed on a captive ball hit.
The motor is controlled by solenoid driver no. 19 (at J125-3 or J126-3).
Do not connect a motor directly. It must be connected via the proper EMI filter.

The Trunk ball saver is generally only active in non-mode play and with the Trunk at its passive position.

Max bonus-x is 8.
