Revision History: (Included for reference)

Version H-6 / H-5 / Profanity roms)

No info is known about the changes with these versions, as far as gameplay / rules (if any).

Both H5 and H6 are FREE PLAY ONLY (cannot be setup for coins)
Both H5 and H6 use a specific set of sound roms which are reduced compression / higher quality sound samples, which is why there are 2 extra roms needed (SU8 and SU9) for this set, and the SU2-SU7 are not the same as the ones used in the standard sound rom set.. (I am not sure if/how well these sound roms will function with the latest LX4 version, so even if seems to work, there may be periods of missing music or sound effects when certain sounds are triggered if you do not run the “home sound roms” with H6/H5 CPU.)

H5 = Upgraded sound quality without Profanity
H6 = Upgraded sound quality with Profanity

The export version supersedes all A ROMs.

Fixed the auto replay system. It was not adjusting.

Version L-3
Date: May 11, 1994
U6: Checksum: B803 (A – USA/Canada)
Checksum: C003 (X – Export)

Changes from revision L-2:

Added a US AIDS awareness message to attract mode.

Fixed the Retina Scan maximum value. It would jump
from 30M to 48M on the jet bumpers. It now correctly
maxxes out at 35M.
Made it harder to jiggle the game during the 3rd
multiball wave to make the cars move and boost
jackpots. (And turn on ball saver.)

Added an adjustment to turn off the speech in match.

Added an adjustment for the car crash ball saver.
CRASH BALL SAVE can be set to EASY (default) to
turn on the ball save with the 2nd opto, or to
HARD to turn on the ball save with the standup target.

Made the claw smarter about the coin door interlock
switch disabling the magnet. When the coin door is
closed, the game checks to see if it thinks the magnet
is broken, and if so, tries to check it again.

Changes from revision L-1:

Revision L-2 MUST be used with the L-2 sound ROMs.

Added a bunch of effects: sound, display, lights.

Added a French AIDS message. (French jumpers and Language only)
Added the rest of the German and French translations.

Fixed two errors in status report. It was showing the
incorrect value for jackpot when multiball was ready,
and it was showing only the super jackpot value when
in multiball.

Changed the stuck handle switch stuff so it checks
for bad switches after it puts one back in service.
And made the claw work correctly when handle switches
are bad.

Changed the default replay boost to 75M. 100M for
export games. Also boosted up the default replay

Changed the logic on the car crash ball saver to
make it immune to players shaking the game to
activate it.

Fixed the combo accounting. The graffiti bomb was
giving 2 combos for the “add combo” award.

Fixed the computer award “collect bonus”. It was not
including the “trigger combo” portion of bonus.

Version L-1
Date: April 19, 1994
U6: Checksum: 8E01 (A – USA/Canada)
Checksum: 9601 (X – Export)

Initial release to production.

Changes from revision P-5:

Fixed an error in status report that made it show the
wrong number of combos to get an extra ball.

Fixed the lamp labels for the M and L rollovers.

Added a few more German translations.

Added code to compensate for the gun triggers getting stuck ON.

Enhanced the Combos a bit. We now enable a combo
on the underground any time a ball is launched
(either by the player or ball save.) We enable
the side ramp for a double combo on any ball save
ball launch. Also, we make the combos do the right
thing when we see a return lane switch if the combos
are not already enable for the correct side of the

Changed a bunch of score values

Added a bunch of effects: sound, display, lights.

Fixed the 5-ball multiball audit. It was not chalking.

Added an (adjustable) extra ball on the Retina Scan.
If it’s adjusted off, an Explode Hurry-up is put
in its place.

Fixed the broken claw or diverter awards so a super
jackpot is possible during multiball when the claw
is broken.

Put a “minor” car chase award on the left and right
ramps. Hitting the car crash lights the lamps solid.
Shooting a ramp with the light on solid gives the
current car crash value.

The game will now complain at power up if none of the trough
optos are working.

Once per game, we will ball save on the left outlane
if the ball bounces out after the eject kicks.

Made the ramps which feed the left or right
return lanes do the Access Claw and Light Quick
Freeze work. This is in case the rollovers are
broken, or in case the ball doesn’t drop correctly
from the ramps.

Added an adjustment for secret features. The default
setting is ON. The secret features can be turned off
only if tournament mode is ON.

Added Demolition Jackpot. It is lit at the end of
the fourth multiball for the rest of the ball.
Shooting the cryoprison awards a bunch of points
for each jackpot shot in each of the multiballs.
