V1.70.0 - Feb 12, 2018
======================

  - Jam Multiball, Album Multiball, and Tour Multiball were not adding
    the points scored from super jackpots to the total.  These have been
    corrected.
  - Improved the lockout of the VIP PASS when a ball is served so there
    is less chance that the player accidentally uses up a VIP PASS when
    launching the ball.
  - Reduced JAM MULTIBALL initial # of shots from 6 to 5.
  - Reduced JAM MULTIBALL increment # of shots from 2 to 1.
  - Reduced JAM MULTIBALL super jackpot lit initial # from 6 to 5.
  - Reduced JAM MULTIBALL super jackpot lit increment # from 2 to 1.
  - Reduced TOUR MULTIBALL initial # of shots from 8 to 7.
  - Reduced TOUR MULTIBALL increment # of shots from 2 to 1.
  - Reduced TOUR MULTIBALL super jackpot lit increment # from 2 to 1.
  - Reduced ALBUM MULTIBALL increment # of shots from 2 to 1.
  - Reduced ALBUM MULTIBALL super jackpot lit increment # from 2 to 1.
  - Changed the rule for the DEVIL HORNS.  Instead of lighting all 3 shots
    at once, they are lit in order: BELL, RIGHT LOOP, LEFT LOOP.  Once the
    LEFT LOOP shot is made to complete the sequence, the Tunes N Stuff lamp
    is lit to collect "STUFF".
  - Added STUFF to Tunes N Stuff:
      - 2X DEVIL HORNS (multiplies the lit DEVIL HORN shots by 2).
      - HOLD BONUS
      - 7,500,000 POINTS
      - AWARD BELL SHOT WITH V.I.P. PASS
          Using the VIP PASS button also awards all features available
          at the BELL (which includes advancing the PLAYFIELD MULTIPLIER).
          (The Premium/LE will swing the bell using the BELL MAGNET.)
      - OI MANIA (7,500 PER SWITCH.  OI!)
      - 10,000,000 POINTS
      - EXTRA BALL
  - Increased DEVIL HORNS value.
  - Changed the presentation of the lights for Tunes N Stuff:
      - JUKEBOX horns blinking = JUKEBOX lit to change a song.
      - Tunes N Stuff light BLINKING = JUKEBOX lit for Tunes N Stuff.
          (If the JUKEBOX is lit ONLY to change a song, then the
          Tunes N Stuff light will be SOLID.)
  - Added a setting to have the target lamps NOT blink when not scored.
    (This is now the default behavior.)
  - Removed the LEFT LOOP shot from always being lit for the WAR MACHINE
    mode.  Completing the spinner during WAR MACHINE will re-light the LEFT
    LOOP WHITE ARROW SHOT for a much lower value.
  - Game over effects are killed when entering test mode.
  - Increased FOR THOSE ABOUT TO ROCK mode cannon shot and playfield shot
    scores.
  - Increased the scores that can be collected from the cannon for starting
    multiballs (JAM, ALBUM, TOUR).
  - Changed the BACK IN BLACK rule so it is more interesting, valuable,
    and potentially takes less work to get the WHITE ARROW NOTE shots lit:
      - Added a moving target that cycles through AC/DC from bottom to top.
      - Hitting the moving target lights all of the WHITE ARROW NOTE shots.
      - The shot that corresponds to the moving target will be +1X what
        it was before, or 2X if it was not available before; the previously
        multiplied shot will revert back to 1X.
          - (A)C/DC - LEFT LOOP.
          - A(C)/DC - LEFT RAMP.
          - AC(/)DC - BELL.
          - AC/(D)C - RIGHT RAMP.
          - AC/D(C) - RIGHT LOOP.
  - Changed the LET THERE BE ROCK rule so it is more interesting, valuable,
    and potentially takes less work to get the WHITE ARROW NOTE shots lit:
      - Added a moving target that cycles through ROCK from top to bottom
        and back again.
      - Hitting the moving target lights all of the WHITE ARROW NOTE shots.
      - The shot that corresponds to the moving target will be +1X what
        it was before, or 2X if it was either 1X or not available before:
          - (R)OCK - LEFT LOOP.
          - R(O)CK - LEFT RAMP.
          - RO(C)K - RIGHT RAMP.
          - ROC(K) - RIGHT LOOP.
      - Once ROCK is spelled, the BELL shot will light for the highest
        multiplier value advanced to on the WHITE ARROW NOTE shots during
        the spell out.
  - Changed the update priority of the background lamp effect for the
    FIRE BUTTON so it will run first and not be excluded by in-game lamp
    effects that cannot run.
  - Increased the ROCK N ROLL TRAIN combo score.
  - Increased T.N.T. scores.
  - Fixed an issue where fading the music volume would cause the music to
    cut out entirely.
  - SLINGSHOT types were not being flagged as such; this has been corrected.
  - Synced knocker to run with replay/special effects.
  - Fixed player up effects so they wait for speech and don't end on a
    blank frame.
  - Fixed switches from showing up in the tech alert when they are not
    broken.  These include:
        TOURNAMENT START BUTTON
        START BUTTON
        LEFT COIN
        CENTER COIN
        RIGHT COIN
        FOURTH COIN
        FIFTH COIN
        DEDICATED #6, #7, #8, #14, #16, #20 (NOT USED)
        TILT PENDULUM
        SLAM TILT (OPTIONAL)
        TICKET NOTCH
        TEST ESCAPE, MINUS, PLUS, ENTER
        DIP #1 - #8
  - Added speech for HSTD enter initials timeout.
  - Combos were not clearing a counter properly, which caused incorrect
    combo values to carry over to other players.  This has been corrected.
  - Corrected the names of the diagnostic buttons (these are translated
    now).
  - Shot multiplier for banked targets reworked to allow additional targets
    at the multiplied value (during a grace period of ~0.25 seconds).
  - Shot-multiplied spinner values via SUPER LANES during ENCORE, WAR
    MACHINE, and regular play may have terminated prematurely (typically
    during multiball) and some spins during a single spinner session may not
    have been awarded at the multiplied value.  This has been corrected.
  - Fixed a bug with the ramp standup targets that would cause the score
    for completing the targets to be one increment too high.
  - Changed "VOLUME" to "ATTENUATION".
  - Cannon eject switch default is NOT accessible.  Accessibility is set
    when the right ramp diverter is activated.  This prevents the cannon
    eject switch from being marked bad when the ball cannot get there.
  - Changed the layout of the pop bumper display effect so the pop bumper
    value is explained better, also to not have two scores next to each
    other.
  - Added a lamp effect for completing the pop bumpers.
  - Any cannon eject switch activity will now release the right ramp
    diverter, to further prevent two balls from getting stuck in the cannon.

V1.68 - Jun. 5, 2014
====================

  - Competition and Director's Cut installs set "SONG LOWER PLFD. ACCESS
    DIFF." to HARD.
  - Added a difficulty adjustment for accessing the lower playfield during
    the songs that utilize it.  When set to HARD (the default is EASY), all
    of the white note arrow shots must be completed before access to the
    lower playfield for the song is granted.
  - Changed the lower playfield rule and scoring for Highway to Hell.
    First, outer loops are made at a low value, then standups are made at a
    low (but slightly higher) value, then a single roving shot is made for
    a high value.
  - Added switch sounds to drop target test.

  - Increased the timer for the shot multiplier.
  - Fixed an issue with tilting while the mode select was active where the
    game would try to request effects and score points during tilt (not
    allowed).
  - Fixed a problem with mode average scores that was causing the scores
    to be averaged incorrectly.
  - Fixed a problem with the game over music being killed when it should
    not have been.
  - Custom message now displayed every pass through the attract mode.
  - Fixed a problem with instant info for the bell (playfield multiplier)
    that was causing the playfield multiplier value to be displayed
    incorrectly.
  - Added speech for lighting the song jackpot via the bottom lanes.
  - Reordered instant info table to display the multiball jackpot
    information in a different order.  The number of items (ramps, target
    banks, loops) to light multiball is displayed first, followed by the
    jackpot information.

V1.65 - Mar. 22, 2013
=====================

  - Synced album multiball/song/target banks state to keep awards from
    being given out of sync (for instance, starting album multiball with
    the T.N.T. song running with "N" and "T" already scored and hitting
    "T" which would start the detonator hurry-up).
  - Fixed a problem with the player controlled cannon.  If the player
    loaded the cannon but did not fire it, then some cleanup work would
    not be performed, resulting in a stale process.  For the PRO, this
    was innocuous, but has been corrected.  For the Premium/LE, however,
    this would cause the drop target bank(s) to not reset properly until
    the cannon was loaded again and fired.  This has been corrected.
  - Fixed a sound call in cannon test.  The enter button was making the
    plus button sound.  This has been corrected.
  - Cannon "missed" speech no longer requested when the left loop, the left
    ramp, or the bell are hit as a result of firing the cannon.
  - Fixed a problem with the background lamp effect for rock n roll train
    not showing the correct combo lamps at times.
  - Rock N Roll Train mode combo shot now marks the white note arrow
    underneath it solid if it was available at the start of the combo.
  - Fixed up VIP pass for the songs.  Priority is now given to the note
    arrows for add-a-ball.
  - Fixed an issue with the song high scores.  In a multi-player game,
    there was the possibility of player #2, #3, and #4 entering their
    initials with a bogus score that they did not legitimately earn.
    Additionally (although no one probably ever saw this), if a player
    scored enough points in their songs to qualify for song high scores
    at the end of the game and then played Encore and won, as long as
    there were players to play after that, then the player who played
    Encore would possibly lose their song high scores for the songs the
    following players played.  This has been corrected.  (This bug is in
    all versions of AC/DC up until now but has somehow managed to go
    unnoticed until 64-bit scoring was introduced as the 64-bit bogus
    scores can be much larger and thus much more noticeably wrong).
  - Added instant info for bottom lanes to light song jackpot.
  - Fixed a bug with the super modes.  Occasionally, a super mode that was
    already running would be chosen as the next mode to start.  If 3
    (adjustable) note arrow shots were made before a Thunderstruck target
    was hit, the mode would be locked on the mode that was already started
    and the only way to recover from it would be to change to the next song.
    This has been corrected.
  - Added an adjustment for "SUPER MODE LOCK/UNLOCK" (default = NO).  The
    super mode lock feature has existed since version 1.0 and allows the
    player to lock/unlock the currently flashing super mode using the fire
    button.  With the addition of VIP pass in V1.6, this feature is now
    almost completely useless, since you either a) never use it because
    you have a VIP pass and don't want to waste the VIP pass to lock in a
    super mode, or b) inadvertently lock in a mode you don't want when using
    the VIP pass for add-a-ball.  Those who would like to re-enable this
    feature may do so by setting "SUPER MODE LOCK/UNLOCK" to YES but I would
    not recommend it.
  - Bottom lanes lamps cleared out when super lanes is started.
  - +/- test buttons now raise and lower the master volume when the attract
    mode radio is on the display instead of bringing up the system "change
    volume" effect.
  - Fixed the beginning segment of "Highway To Hell" (too much silence).
  - Implemented station band changing (AM/FM) for the attract mode radio via
    the fire button.  The FM band plays studio songs, and the AM band plays
    live songs.  May change to FM1/FM2.
  - Added attract mode radio (adjustment must be set to YES (default is NO)
    and FREE PLAY set to enable).  Hold in the right flipper button during
    attract mode to bring it up.  Left and right flippers change the station,
    both flippers cancel.  Probably for free play/home use only.

V1.63 - Jan. 18, 2013
=====================

  - Added multiplied shots to "For Those About To Rock".
  - The bell shot is now part of combos via the left loop and the right
    ramp.
  - Fixed an issue that would possibly corrupt the auto extra ball data.
  - Added lamp effects for T.N.T. awards.
  - Album multiball and tour multiball jackpot information now displayed
    outside of multiball.  This helps the player if they are trying to
    change songs to set up a song bonus.
  - Added art and sounds for double/triple bonus.  Bonus intro now plays
    in the key of the song that was being played.  2x/3x stamp is either
    fire or lightning (instead of silent screen flip) based on what song
    was being played.
  - Added speech for good bonuses.
  - Added super jackpot speech.  Added big lamp effects for cannon
    target(s) hit.
  - In an effort to keep two balls from jamming up in the cannon, the
    control gate that diverts the ball into the cannon will release the
    gate if a second ball arrives at the right ramp exit switch
    immediately after the gate was closed to divert the first ball.
  - Encore "won" and "keep shooting" effects may no longer be aborted.
  - Some sound test music was being cut off during sound test.  This has
    been corrected.
  - Fixed an issue with the song intro loop music being trampled when
    the ball is loaded into the cannon quickly at the start of a new ball.
    Very noticeable on songs with lengthy intros, like "Back In Black"
    and "For Those About To Rock".
  - Added some lamp effects.
  - All scores (system and game) are now stored as 64-bit.
  - Fixed up the audits.  3-multiball super jackpot and all encore audits
    were not being displayed.  This has been corrected.
  - Added audits for the top eject and cannon switches.  Triple multiball
    super jackpot is now always available (but will still reset when
    collected).
  - Ramp targets now score like the other targets, where the value that is
    built up during the ball is reset at the start of a new ball.
  - If the player does not fire the cannon (timeout), most cannon awards
    will not remain available.  They will have to be requalified.  This
    prevents certain exploits (i.e. firing the ball at the left loop to
    get +1 advance for Tour Multiball along with (usually) a note arrow
    during a song).

V1.61 - Oct. 30, 2012
=====================

  - Lower playfield states for the lower playfield modes are now
    initialized each time the mini-playfield is activated.
  - Changed the color of the roving shot for the thunderstruck mode.  The
    roving shot is a lighter blue than the normal shot.
  - When paging through instant info during JAM MULTIBALL with the JAM
    MULTIBALL super jackpot lit at the cannon, the info screen would say
    "TOUR MULTIBALL SUPER JACKPOT LIT".  This has been corrected.
  - Roving shot for thunderstruck mode now awarded first when using VIP pass.
  - Added jam/album/tour multiball start speech.
  - Changed the thunderstruck rule.  Hitting a roving standup target now
    lights all of the white arrow shots and starts a roving shot across the
    white arrow shots from the left loop to the right loop and back again.
    The value of the roving shot starts at 2x and can be increased by
    hitting another roving standup.  Each new standup hit raises the value
    of the roving shot by 1x.  Once the roving shot is hit, it is turned
    off, and the player must hit one of the thunderstruck standup targets
    to light it again.
  - Super skill shot awards 2 VIP passes.
  - Combo, lanes, loop, and target bank jackpots are now unregistered if
    the cannon shot is missed.
  - Fixed a bug with the specification of the ticket meter for the game.
    The old specification would only allow the ticket meter to be fired if
    the "TICKET DISPENSER TYPE" adjustment was set to "DELTRONIC WIDE".
    This has been corrected.
  - Implemented music and sound volume.

V1.6 - Sep. 7, 2012
===================

  - Cleaned up hell mode logic with the lower playfield.  The lower
    playfield is available at the start of each "Hell" song.  Once the
    lower playfield feature has been played, it is made unavailable
    until all of the white note arrow shots for the song have been
    completed.
  - Fixed the user-controlled magnet hit during the "Hells Bells" mode.
    The bell opto is now ignored for one second when the ball is kicked
    from the bell eject hole.
  - Bell magnet cleanup.  Hells bells now swings the magnet when the VIP
    pass is applied (via the FIRE button).
  - Added general illumination intensity level adjustment.
  - Added RGB LED test to make it easier to dial in some colors for the
    multi-colored LEDs.
  - Fixed a bug with the mechanical band during "You Shook Me All Night
    Long".  The band would not move during the last 10 bars of the song.
    This has been corrected.
  - Designed RGB LED and LED GI effect systems & implemented effects.
  - Added encore mode for playing all songs in the jukebox.
  - Added new artwork for Back In Black / Encore.  "Jukebox Is Lit" speech
    now only requested if the song
    can be changed (i.e. not during multiball).
  - Toned down spinner and pop bumper flasher effects.
  - Broken targets are now removed from consideration when targets are
    selected at the start of the cannon firing sequence.  Fixed cannon
    message "HIT TARGET FOR".  This will say: "HIT TARGETS FOR" when there
    is more than one target lit in the sequence (such as a latter stage
    of FTATR and encore FTATR stage, for example).
  - Disabled target banks, loops, and ramps during encore.  Enabled top
    lanes and pop bumpers (under certain circumstances).  Cleaned up stages
    to make some of them more challenging.  Added lamps in the jukebox for
    completed stages.  Secondary shots add to the song jackpot and give
    add-a-ball.  Draining resets the song jackpot value.  Added some
    reasonable scoring.  Cleaned up shaker motor code.  Control gate now
    works as expected during encore rosie and shook me.
  - Added instant info to the cannon for encore.
  - Each encore stage, when completed, now scores the song points scored
    during the game.  Added an adjustment for the number of balls for
    encore.
  - Fixed an issue with recording mode average scores.  These were not
    taking into account the number of times encore was started.  This has
    been corrected.
  - Added art and sound for "SPECIAL".
  - Added art and sound for "Back In Black" start.
  - Added a lamp effect for multiball start.  Added "EXTRA BALL" and
    "SPECIAL" lamps to most lamp exclude strings.
  - Changed all of the default song HSTDs from 5M to 7.5M.
  - Added a lamp effect for extra ball.
  - Changed the sequencing of the cannon award effects.  These run
    immediately (if possible, they are VERY high priority) and will
    interrupt almost any other effect.  Sped up the display of the
    cannon shots that are available when the cannon is ready to be
    fired.
  - Lane change disabled when picking a song.  Fixed up instant info
    for VIP passes.  Removed unused instant info lamp effects.
  - Added bell hits for playfield multiplier to instant info.
  - Added VIP pass.
  - Fixed a bug with double/triple bonus.  If triple bonus was earned,
    double bonus would be given instead of triple bonus.  This has been
    corrected.
  - Reworked "super mode" jackpots.  These are no longer lit from note
    arrow shots during the songs.  Combo jackpot is lit every 20 combos
    (adjustable).  Lanes jackpot is new and lit every 10 bottom lane
    completions (adjustable) -- top lane completions increase the value.
    Loop jackpot is lit every 15 loops (adjustable).  Target bank jackpot
    is lit every 10 target bank completions (adjustable).
  - Target bank extra ball #2, target bank special #2, combo extra ball #1,
    and combo extra ball #2 could not be adjusted off.  This has been
    corrected.
  - Added target bank extra ball and target bank special to Instant Info.
  - Fixed a typo in the adjustment table that had the incorrect value for
    the MEDIUM settings for the number of bell hits for the playfield
    multiplier.
  - Added speech for lighting the jukebox.
  - Added tilt and drain speech.  Due to certain profanity that was added,
    the default value for the "Family Mode" adjustment is now "ON".
  - Fixed up the cannon motor movement sounds.  The sound was being cut off
    at the mark switch when it was almost at the home switch.  Now, the
    sound plays for the duration of the movement.  This has been corrected.
  - Changed the bell sound track such that the sound effect should almost
    always be heard.
  - Added new rosie jiggle art for white arrow note shot.
  - Changed the cannon firing sequence.  If the player did not fire the
    cannon (i.e., a timeout), the ball would be fired out of the cannon
    when the MARK switch made a transition.  On some games, the ball would
    make it up the right ramp for free awards.  Now, if the cannon is not
    fired by the player, the cannon will return to the HOME position with
    the ball and then start another sequence which will auto-fire the ball
    out of the cannon somewhere in the direction of the AC/DC targets
    (with the appropriate speech, which is a little clearer).
  - Changed starting song jackpot to increase as songs are changed.
  - "For Those About To Rock" was not keeping the note arrow(s) solid when
    the shot(s) had been completed.  This has been corrected.
  - Added art for the start of the "Hell Ain't A Bad Place To Be" mode.
  - Added multiball mini super jackpot.  If all three multiballs (Jam,
    Album, and Tour) are started at the same time, then a mini-super jackpot
    will light at the bell once at least one each of: ramp jackpot, target
    jackpot, and loop jackpot have been scored.  Once the mini super
    jackpot is lit, each additional jackpot scored will be added to the mini
    super jackpot.  Once the mini super jackpot is collected (by hitting
    the bell), the mini super jackpot is reset, and one each of all jackpots
    will need to be collected again for it to be available again.
  - Jam, Album, and Tour multiball jackpots from the cannon are now
    multiplied, based on the number of multiballs started.  1 multiball =
    1X jackpot, 2 multiballs = 2X jackpot, and 3 multiballs = 3X jackpot.
  - Added lit cannon items and their values to instant info (this includes
    song jackpot).
  - Added new sounds for tilt warning.  These are much louder than the system
    default sounds.

V1.52 - May 30, 2012
====================

  - Added lots of shaker motor effects.
  - Added sounds for hitting a flipper button during the attract mode.
  - Removed super combos and super loops information about collecting the
    jackpot; it was taking too long when the ball was diverted into the
    cannon.
  - Increased the cannon motor timeout from 7.5 seconds to 15 seconds.  7.5
    seconds was not long enough for some slow-running motors.
  - Added some functionality that allows the ticket dispenser test to show
    up when the ticket dispenser has been enabled.
  - Changed the artwork for the right loop award.
  - Added lamp effects for ramp target hit and ramp entrance made.
  - Added broken switch detection for the fire button that kicks in much
    sooner than before.  If the cannon can be fired and is not (no fire
    button sw. seen during the firing sequence) for 3 sequences in a row,
    then the next sequence and all of those that follow will allow the
    cannon to be fired using either of the flipper buttons.  The fire
    button can be "healed" when there are 2 sequences in a row that use
    the fire button to fire the cannon (instead of a flipper button).
  - Added the top lane and the bottom lane lamps to the "fire the cannon"
    lamp effect so the player can use lane-change (in case of multiball).
  - Added things lit at the cannon (song jackpot, collect bonus, etc.) and
    their values to instant info.
  - Added collect bonus every 8 (default, adjustable) pop bumper levels.
  - Added art and sounds for extra ball lit and special lit.
  - The back panel flasher was missing from the lamp effects.  This has been
    corrected.
  - T.N.T. mode was allowing spurious hurry-up awards on the T.N.T. targets.
    If two T.N.T. targets were hit at the same time where the first target
    hit was a target that completed the T.N.T. sequence to start the hurry-
    up and the second target hit was any T.N.T. target other than the first,
    then the spurious hurry-up award would be given.  This has been corrected.

V1.5 - April 27, 2012
=====================

  - Removed the definitions for the lower playfield end-of-stroke switches,
    as these have been removed and were never in any of the production games.
    So now they will no longer be reported in Tech Alert.
  - The upper playfield flippers were not being turned off during "Hells
    Bells" and "Highway To Hell" when the ball was held and the lower
    playfield was being played.  This has been corrected.
  - If the ball leaves a device while the lower playfield is being played,
    the upper playfield flippers will be turned back on.
  - More time was added to settle the bell eject after a kick.
  - Playfield multiplier now paused when the lower playfield is active.
  - Added backgrounds for "Hells Bells" and "Highway To Hell" lower playfield.
  - 2X, 3X, and jukebox song title lamp states are now displayed when the
    lower playfield is active.
  - Removed lamp effects that manipulated the G.I. relay.
  - Ball search for the bell magnet was not ignoring the bell opto switch
    and keeping it from scoring a hit on the bell.  This has been corrected.
  - Fixed a resource conflict with the song select G.I. backgrounds.  These
    now work as intended.

  - Completing all of the white note arrow shots during a song now adds 2.5M
    to the song jackpot.  This can be done any number of times.
  - Timers are now paused when the player is choosing a song.  (This fixes the
    issue of the ball saver timing down at the start of a new ball when the
    player plunges the ball into the jukebox and takes some time picking a new
    song.)
  - Added artwork for the start of "Hells Bells".
  - Added a sound for tilt.
  - All white note arrow shots completed during a song records 3 units of
    permanent progress (one time, adjustable), such that completing notes
    and changing songs will continually lock in higher scores for new songs.
  - Super loops no longer has any effect on whether the right control gate
    causes the ball to loop around, so if "Whole Lotta Rosie" or "You Shook
    Me All Night Long" are running, the ball will go into the pop bumpers.
  - Added jackpot information to the super loops award display effect.
  - Added sounds for "Let There Be Rock".
  - Cannon targets are now displayed in order of increasing score.
  - Added song jackpot to tour multiball.
  - Changed the lamp effect for a spinner hit during "War Machine".
  - Added a sound for the War Machine bay doors opening.
  - Lowered spinner scores.

V1.21 - February 2, 2012
========================

  - Initial release.

System V1.66
Changes since V1.60:
====================

  - Fixed a problem that was causing the audit display "N% OF GAMES" (N)
    to be displayed incorrectly for some audits.
  - End-of-game HSTD processing (enter initials, etc.) was not checking
    to make sure it was OK to collect initials and record high scores
    (i.e. the ALLOW HIGH SCORES adjustment, when set to NO, was not being
    honored).  This has been corrected.
  - RTC default time changed to January 1, 2014.
  - Fixed potential divide by zero exception when computing the number
    of bars to draw for the progress bar when verifying the flash image at
    power-up.
  - Added a vertical offset for the equal sign (=) for the 3x7 and 3x7
    outline fonts.  These characters are now rendered properly.
  - First pass of the redemption system.
    see http://www.sternpinball.com/downloads/Stern_Pinball_Redemption_System_Software_Manual.pdf
    for details.
  - Changed trough test to accommodate switch numbers that are larger than
    2 digits.

    the 5x7 font so we can have more characters on the screen.
  - Added USA 11 pricing.
  - Fixed Italian text that would not fit on the display.
  - Fixed a problem with the ball save lamp.  There was a chance that the
    ball save could time down without the player ever seeing the ball save
    lamp blink down during the timeout.  This has been corrected.
  - Occasionally, when setting or retrieving the attenuation associated
    with a sound track, the attenuation would be set or retrieved for the
    wrong track.  This has been corrected.
  - Sped up the start of instant info when the ball is sitting in the
    shooter lane.
  - Changed the 5x5 and the 5x5 outline comma character.  Fixed the
    vertical offset for the 5x5 outline font equal character.
  - Added new Australian coinage/pricing table.
  - H.S.T.D. "enter initials" display effect was not auto-sizing the line
    that displayed the name of the high score that was achieved.  This has
    been corrected.
