No Fear: Dangerous Sports Pinball – CPU Rom 2.3X [U6] [Bally / Williams] EPROM

(This listing is the most current official release)

Revision History: (Included for reference)

Version 2.3
Date: September 14, 1995

U6: Checksum: CC23 (A – USA/Canada)
Checksum: B023 (X – Export)

Changes from revision 2.2:

Improved the ball search logic to better compensate for a
broken switch at the right popper.

Changed the Skill Shot choice to start after the plunge,
not before. This keeps the choice from being available
until the ball actually arrives at the shooter.

Fixed a bug where choosing LOCK from the skill shot would
remove the 3rd lit lock if the player already had it lit.

Fixed score histogram labels.

Version 2.2
Date: September 14, 1995
U6: Checksum: A622 (A – USA/Canada)
Checksum: 8122 (X – Export)

Changes from revision 2.0:

Fixed a bug where the state of the errors for the optos
being stuck and the drop target being flakey were not
being cleared at factory reset, so the user could get
erroneous errors randomly, based on the state of the CMOS
RAM before the reset.

Fixed a bug in the user-error report where line 2 of
of the error message was not being cleared properly.
This would cause messages such as “check drop target,
not set” instead of just having “check drop target”

Version 2.0
Date: June 8, 1995
U6: Checksum: C520 (A – USA/Canada)
Checksum: 9F20 (X – Export)

Changes from revision 1.1:

The game now checks the ramp magnet optos to see if any are stuck
closed at initialization. If so, they are considered to be
disabled until the next powerup (or test mode) that sees them
un-stuck.

Added user report messages for stuck and disabled magnet optos.

Changed broken switch logic on drop target to make sure
that it does not try to change the position of the drop
target unnecessarily; thus allowing the player to get
to the shot behind it more easily. This then allows
locks to be lit much easier when the drop target is broken.

Added logic to watch the drop target for 15 games to make sure
that is is lighting locks. Gives a message if 15 games go by
without a lock.

Corrected the updating of the buy-in button lamp to make sure it
is updated whenever credits are added. Before, it would not start
blinking until the player had put in MORE than the required credits
for buying in.

Allowed the buy-in button to enter initials during the high score
to date entry screen.

Changes from revision 1.0:

Changed the default adjustment for Raceway Start to AUTO.

Change the default Raceway Holdover Difficulty to HARD.

Changed the auto-percentage of Raceways to start with 2 lit
instead of 3 by default.

Implemented the “dice match” feature. Added an adjustment
to use the old match display.

Fixed a glitch in the multiball start display.

Changes from revision 0.8:

Added German translations.

Fixed a bug in the drop target updater which would allow
the drop target to stay in the “wrong” state if it was
told to change while it was already busy trying to change.

Changed track feature to allow laps during the grace
period of nascar – the most obvious result of this is that
the nascar lamps will be properly updated at the end of
NASCAR mode.

Drop target now only makes a sound effect when it is dropped
by the player.

Added adjustment ofr attract mode sounds and speech.

Added broken switch logic for right ramp, underground lockup,
right/left loop switches and right return lane.

Trough test now makes sure the drop target is down at the
b eginning of the test.

Added two score fonts to the system to accomodate a 10 billion
single player score and a 10 billion multi-player “player up” score.

Increased flipper Skill Shot to 50 million.

Fixed “match” text to fit on screen.

Added a bunch of lamp, display and sound effects.

Ball search is now held off during video mode.

Fixed up the auto-plunger to correctly check game over conditions.
