- "T-play": When tournament play selected: As the "Pattern" option. Else as the "Random" option.

Default: "T-play".

New feature adjustment A.2 20 "Tournament play Snack bar Unlimited millions".
- "No": When tournament play selected: The Snack bar will never award the Unlimited millions mode.
- "Yes": When tournament play selected: The Snack bar will award the Unlimited millions mode (see awards pattern).

Default: "No".

The 10B Snack attack bug, fixed.
Snack attack count down lands nicely on 10M.

255 bumper hits to light Super jackpot bug, fixed.
Bumper hits to light Super jackpot not resetting on a next multiball bug, fixed.

1x “maxed” playfield multiplier bug, fixed.

Bonus-x calculation corrected to be as indicated by the game. 1x/2x/4x/6x/8x/10x.
Bonus base value raised by a factor-3.

A bug where Move your car was not running properly after a multiball, fixed.

A bug where Snack attack was incorrectly promoted on the right ramp count-up display, fixed.

When tournament play selected: Playground award is following a fixed pattern. Player individual.
Playground award order: Unlimited millions, Jet bumpers, Intermission time and then start over.

When tournament play selected: Snack bar awards follow a fixed pattern. Player individual.

When adj. A.2 20 "Tournament play Snack bar Unlimited millions" is set to "No":
Before a multiball has been played: F, L or M letter once (if needed and in that order). Then random points ones.
After a multiball has been played: Random points ones only.

When adj. A.2 20 "Tournament play Snack bar Unlimited millions" is set to "Yes":
Before a multiball has been played: F, L or M letter once (if needed and in that order). Then random points ones.
After a multiball has been played: Unlimited millions once. Then random points ones.

When tournament play selected: Tap a button in attract mode to show the latest game scores.

The 10M, 20M and 30M indicators are brought to life.
The Big millions mode offers a one time only award on the left inlane.
10M, 20M or 30M based on timing.

A bug where the European region installs the hard pre-set on a factory reset, fixed.

The lamp matrix procedure is upgraded to better prevent "ghosting" when LED lamps are used.

Adjustment A.1 21 "Language" is limited to "English".

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


The Snack bar Unlimited millions, after a multiball played, is any multiball played.
When selected, the Unlimited millions mode is victory laps for the multiball.

Snach bar random points ones are: Popcorn (1M), Hot dog (2M), Hot pretzel (4M), Ice cold pop (4M) and Hamburger (5M).

The incremented bonus base value is to compensate that the max bonus-x is reduced from the incorrect 32x to 10x.
High X bonus is by this a similar payoff. Low X bonus will get a boost.

Feature adjustement A.2 3 "Multiball" is of no use.
At least as of rev. L-4, the game is not awarding multiball at the Snack bar mystery.

The Big millions mode left inlane award is also given when the inlane is made on a ramp shot return.
In L-4, the indicators were used for light show only.
The Big millions mode is also running during Super scoring. But will end (time out) before the Super scoring umbrella mode is ending.
