Game Code Update - REV5 Mousin Around (2 Chips)

 ANNOUNCING: NEW FOR 2021! Updated Game Roms - Under license from Williams Electronics Games, Inc and Planetary Pinball Supply. 

As part of Planetary Pinball Supply, Inc. License with WMS, we have received approved to make available modified game code via EPROMS that PPS as well as a number of other AUTHORIZED suppliers have available. 

This is done in collaboration with Soren Worre, who is a talented software developer who is fixing original game flaws or adding enhancements to improve the overall game play. 

Note, that PLEASE support this effort as we have setup a number of authorized suppliers. If we have people selling this without authorization or distributing binary files (both of which are a violation of copyright as well as WMS licensing agreements), then we may stop this activity. We are planning enhancements to many games, and support within the pinball community will help fund Soren so he is motivated to continue. The following suppliers are authorized - you can verify as these EPROMS will ONLY have a BLUE serial numbered hologram on them - without these they are counterfeit, and please contact PPS in that case! - Matt's Basement Arcade - Classic Arcades - Action Pinball - Astill Amusements - dotsandloopspinball.com (Soren Worre) - Planetary Pinball

Based on the revision LA-4 software released in 1989 by Williams Electronics Games Inc.

The author would like to thank the designers of this pinball machine.

Summery

New feature adjustment adding runmodes to the target bank and center ramp.
Bug fixes.

Improvements

Limits the repeat shot play of the center ramp returning to same flipper.
Reward for controlling a streak of shots to same ramp without hitting other shots.

Detailed changes description

Reference to the LA-4 revision.
Some of the description is not a change as such. But features present in the LA-4 revision too.
Withtaken to give a complete overview of how the target bank and center ramp works.

Adjustment 33, Motor bank, has been given the two additional options. Cheese and Streak.

Cheese:
1-2-3 targets made carry cross-balls, player individual.
If CHEESE is completed, a center ramp shot will close it.
If CHEESE is completed on a center ramp shot, it will close right away.
Locks made and multiball will not close the center ramp.
Collecting jackpot will not close the center ramp.

Streak:
Same as "Cheese" option in addition to.
If CHEESE spell out was completed only on the center ramp, from when the center ramp was opened,
a "Streak bonus" of 100K for each letter collected on center ramp is given.
Like this.
”CHEESE” on center ramp = 600K Streak bonus.
”HEESE” on center ramp = 500K Streak bonus.
”EESE” on center ramp = 400K Streak bonus.
”ESE” on center ramp = 300K Streak bonus.
”SE” on center ramp = 200K Streak bonus.
Last "E” on center ramp = no Streak bonus.

The Streak option is default on hard and extra hard pre-sets.

New "Streak run" display on center ramp shots, when a streak run is active.
New "Streak bonus" display (with "Go for the hole" sound call) on collect.

Center ramp display was incorrectly "Trap lane bonus".
Now changed to "Ramp loop", on shots out of a streak run (any configuration).

For the light kickback rule (3 center ramp shots), the counter is now reset at start-of-ball.
In Cheese/Streak modes: A center ramp shot closing the ramp will always light kickback.

A bug where the Increase score lamp would stay lit on next ball-in-play, fixed.
A bug where the Double scoring countdown display would stay active on next ball-in-play, fixed.
A bug where the MILLION and Build jackpot light show would stay active on next ball-in-play, fixed.

Note

Adjustment 33 has the following five options, per rev. LA-4, which are kept unchanged.
Ex. easy: 3-bank stays down rest of game.
Easy: 3-bank resets at start-of-ball. 1-2-3 targets made are preserved cross-balls, player individual.
Medium: 3-bank resets at start-of-ball.
Hard: 3-bank resets on Cheezy bonus collected. 1-2-3 targets made are preserved cross-balls, player individual.
Ex. hard: 3-bank resets on Cheezy bonus collected.

And the new settings for comparison.
Cheese: 3-bank resets on Cheezy bonus collected and on center ramp made when CHEESE. 1-2-3 targets made are preserved cross-balls, player individual.
Streak: 3-bank resets on Cheezy bonus collected and on center ramp made when CHEESE. 1-2-3 targets made are preserved cross-balls, player individual.

Every center ramp made still pays 100K on its own. The Streak bonus is extra.
A maxed Streak bonus sequence is 1.4M, all told, on 9 shots.

In rev. LA-4, the 3 center ramp shots to light kickback counter was shared between players. Considered a bug.
The counter is now reset each start-of-ball, and not reset when the center ramp is closed per collection of Cheesy bonus.

The European ROM defaults to the hard pre-set. This revision, based on the US ROM, defaults to the medium pre-set.
The hard pre-set is recommended.
